arm and arm64 have distinct headers, but mips and mip64, and x86 and x86_64
use headers that work for both widths. So where arm/arm64 need to handle the
second architecture case specially, all we need to do for the others is
hard-code the name. (x86_64.mk already hard-codes x86; we need to change
x86.mk for the case where we're building the 32-bit binaries for a mixed
system. mips64.mk doesn't exist yet, but when it does, it'll hard-code
just plain "mips" too.)

To ease the transition between toolchains, allow a target to specify
a list of cflags that the toolchain does not support. These will be
filtered out of the cflags provided by the module.
Add TARGET_GLOBAL_UNSUPPORTED_CFLAGS := -fstack-protector for the
aarch64 toolchain, it does not yet suport -fstack-protector.

This should never have been on the default include path.
The NDK statically links its own libthread_db, so I'm removing
bionic's unused copy from devices.

Allow modules to generate source into $OUT/gen, which will then
be copied into $OUT/obj and $OUT/obj_$(TARGET_2ND_ARCH) as
necessary. This allows a single build rule invocation that includes
generated source to build for the first and second architectures.
Modules will need to change calls to local-intermediates-dir into
local-generated-sources-dir.

Using LOCAL_MODULE_PATH in a shared library module while building a
multiarch target will cause build rules for both architectures to install
into the same path. Warn and suggest LOCAL_MODULE_RELATIVE_PATH.

Most users of LOCAL_MODULE_PATH are setting a subdirectory of the
normal install path, for example to install HALs into system/lib/hw.
This is problematic for multiarch builds, where the install location
depends on the arch. Allow modules to specify LOCAL_MODULE_RELATIVE_PATH.
HALs will generally use:
LOCAL_MODULE_RELATIVE_PATH := hw

We have no rigorous way to detect whether the code referenced for this
mechanism changes in between builds. So declare this as a phony target
so that it is rebuilt every time.

Sometimes it is useful to be able to tell ota_from_target_files
to not sign the output zip file. For instance, the private
release key may not be available when ota_from_target_files
is executed; similarly the release tools may not be available
or executable where the private key is stored.
This change adds an option, '--no_signing', to simply output the
unsigned OTA zip file, instead of spuriously signing it with the
test key even though the zip file would need to be re-signed later
with a different key.

Compiling for arm requires using the arm kernel headers and not
the aarch64 kernel headers. Add $(combo_2nd_arch_prefix) to get
asm-$(TARGET_2ND_ARCH) when arm is the 2nd arch.

With those variables, you can set up different values for TARGET_ARCH
and TARGET_2ND_ARCH.
Also fixed a couple of variables.

By default, an executable is built for TARGET_ARCH.
To build it for TARGET_2ND_ARCH in a 64bit product, use:
LOCAL_32BIT_ONLY := true
To skip a module for TARGET_2ND_ARCH, use:
LOCAL_NO_2ND_ARCH := true

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.

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.
