Ying Wang 98ae798535 Fix using variable intermediates.COMMON before defining.
In commit e9dd9f2bf we moved "include $(BUILD_SYSTEM)/android_manifest.mk"
forward before the variable intermediates.COMMON gets defined. That's a
mistake.
This change replaced the tentative variables
package_expected_intermediates_COMMON and guessed_intermediates with
their proper counterparts defined in base_rules.mk.
If their values differ in the two file, that's an error and we should
fix.

Ying Wang d8c5ca9e0d Allow to strip everything for only some build variants.
When LOCAL_STRIP_MODULE is keep_symbols, you can still use
STRIP_EVERYTHING_BUILD_VARIANTS in product configuration to strip
everything for some build variants, such as user build to save image
space.

Ying Wang 966c1e0cae Add HOST_PREFER_32_BIT to support 32-bit-by-default multilib build
We already support pure 32-bit and 64-bit-by-default multilib build.
With HOST_PREFER_32_BIT we can build 32-bit-by-default multilib build.
This will be lest disruptive during the period we transition to
64-bit-by-default.

Ying Wang 6feb6d5607 Support host multilib build
This change basically ported our target multilib to the host side.
It supports 2 host build modes: x86 and x86_64 multilib build.
For now you need to set "BUILD_HOST_64bit=true" to switch to x86_64
multilib build. Later we'll default to x86_64 build and have a flag
to force 32-bit only build, which may be needed by SDK build.

In host module definition, like in target ones, you can use the
following
LOCAL variables to set up multilib configuration:
LOCAL_MULTILIB: can be "both", "first", "32" or "64".
It also supports the same set of arch or 32-vs-64 specific LOCAL
variables.
By default, it builds only for the first arch.

To keep path compatibility, in x86_64 build files are still output to
out/host/linux-x86; Both 32-bit and 64-bit executables are in
out/host/linux-86/bin;
In x86_64 build 32-bit shared libraries are installed to
out/host/linux-x86/lib32
and 64-bit shared libraries are installed to out/host/linux-x86/lib;
32-bit object files are output to out/host/linux-x86/obj32 and 64-bit
object files
are output to out/host/linux-x86/obj.

Colin Cross 5a9db90e40 add support for LOCAL_MODULE_STEM_32 and LOCAL_MODULE_STEM_64
Some executables will need to be built for both 32-bit and 64-bit.
For linker/linker64, debuggerd/debuggerd64, and a few more, they
will be installed in the same path (/system/bin), but with different
filenames.  Allow the module to specify LOCAL_MODULE_STEM_32 and
LOCAL_MODULE_STEM_64 to name the two versions.

Christopher Ferris a6e2f9322c Add a method to leave the symbol table in a library.
When LOCAL_STRIP_MODULE := keep_symbols is set, then the normal strip rules
will be modified so that only the .debug_* sections are removed. The original
symbol table is left alone.

This allows the compilation of certain libraries so that libbacktrace library
can provide meaningful names to functions.

and TARGET_2ND_ARCH.
Also fixed a couple of variables.

Ying Wang 4d2cc665ea Set up rules to build shared libraries for TARGET_2ND_ARCH
The rules for the 2nd arch are set up in the second inclusion
of shared_library_internal.mk.
Intermediate fils of libfoo of the 2nd arch will be built into
$(PRODUCT_OUT)/obj_$(TARGET_2ND_ARCH)/SHARED_LIBRARIES/libfoo_intermediates/
and the built libfoo.so will be in
$(PRODUCT_OUT)/obj_$(TARGET_2ND_ARCH)/lib.

Ying Wang 1d274d2686 Load compiler environment for a second arch.
This is the first step to build 32-bit libraries in a 64-bit product.
It will work like this:
1) In the product's BoardConfig.mk, define:
TARGET_2ND_ARCH, TARGET_2ND_ARCH_VARIANT, TARGET_2ND_CPU_VARIANT.
The build system uses those variables to set up an additional compiler
environment for the second arch.

2) When parsing Android.mks, the build system sets up rules to build a
module for both the 1st arch and the 2nd arch, unless it's explicitly
asked to skip so.
Android.mk will be adapted if there is additional rule of generating
source files.
The build system will accept arch-specific LOCAL_ variables, such as
LOCAL_CFLAGS_arm, LOCAL_CFLAGS_armv7-a-neon, LOCAL_CFLAGS_cortex-a15,
LOCAL_CFLAGS_aarch64 etc. Modules use such variables to set up build for
various archs at the same time.

3) Install binary of the 2nd arch by adding "<module_name>:32" to
PRODUCT_PACKAGES. All 2nd-arch libraries linked in by "<module_name>:32"
will be installed automatically.

Ying Wang 2408479cf9 Allow module to specify LOCAL_INSTALLED_MODULE_STEM
With this change, you can install a shared library with module name foo
as bar.so to the system.img with:
LOCAL_INSTALLED_MODULE_STEM := bar.so
Note that we in general still disallow a static/shared library to
specify LOCAL_MODULE_STEM or LOCAL_BUILT_MODULE_STEM, because the build
system uses LOCAL_MODULE to compute build time dependencies, such as
export_includes, the -l linker flag etc.
Also, if you use LOCAL_INSTALLED_MODULE_STEM to change the installed
file name and if any other module links against this library, you may
run into runtime error: the library name baked in to the binary is not
the same as file name in the system image.

Iliyan Malchev b375e71d30 build: remove prelinker build build system
This patch removes support for prelinking from the build system.  By now, the
prelinker has outlived its usefulness for several reasons.  Firstly, the
speedup that it afforded in the early days of Android is now nullified by the
speed of hardware, as well as by the presence of Zygote.  Secondly, the space
savings that come with prelinking (measued at 17MB on a recent honeycomb
stingray build) are no longer important either.  Thirdly, prelinking reduces
the effectiveness of Address-Space-Layout Randomization.  Finally, since it is
not part of the gcc suite, the prelinker needs to be maintained separately.

The patch deletes apriori, soslim, lsd, isprelinked, and iself from the source
tree.  It also removes the prelink map.

LOCAL_PRELINK_MODULE becomes a no-op.  Individual Android.mk will get cleaned
separately.  Support for prelinking will have to be removed from the recovery
code and from the dynamic loader as well.

Jeff Brown 703e7c6d50 Build system tweaks for Valgrind.
Added LOCAL_NO_CRT to enable building executables that do not link
to the C runtime library.

Removed support for LOCAL_MODULE_SUBDIR since it was broken
and unused.  (Was going to use it but ended up using LOCAL_MODULE_PATH
instead.)
