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.

/system/lib always contains 32-bit libraries, and /system/lib64 (if
present) always contains 64-bit libraries.
Move things around a little bit, so TARGET_ARCH can be used to define
the build paths.

We currently have two types of host libraries, those
meant for the host VM (Sun, OpenJDK etc.) and those meant
for a host dalvik build. The former need to be compiled
against the host standard libraries and the latter need
to be compiled against libcore. This change introduces
two new build rules to complement the existing the existing
host rules.
BUILD_HOST_DALVIK_JAVA_LIBRARY : Build a java library for
a host build of dalvik. Bootclasspath will be set to a host
build of libcore.
BUILD_HOST_DALVIK_STATIC_JAVA_LIBRARY : Build a static java
library for a host build of dalvik. Bootclasspath will be set
to a host build of libcore.
This change also removes support for the LOCAL_BUILD_HOST_DEX
flag, which is now unnecessary.

The new option WITH_STATIC_ANALYZER=1 instructs build system to
run static analyzer via "clang --analyze" on a successful build.
If analyzer finds any issue, instruction to open report is displayed.
See http://clang-analyzer.llvm.org/scan-build.html for details.
WITH_STATIC_ANALYZER trumps WITH_SYNTAX_CHECK if both exist.
Project use lots of GCC extensions (eg. nested function) not supported
by clang may opt out by adding LOCAL_NO_STATIC_ANALYZER:=true

The new option WITH_SYNTAX_CHECK=1 instructs build system to invoke
"clang -fsyntax-only" to utilize clang's better diagnostics before calling
LOCAL_CC/LOCAL_CXX for code generation. The compilation time is slightly
longer, and the generated object file should be the same as w/o WITH_SYNTAX_CHECK

AndroidProducts.mk allows for a maxdepth of 4 in device and vendor while
vendorsetup.sh and BoardConfig.mk only allow for smaller depth.
Make search depth consistent for these files.
