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.

32 bit targets will leave TARGET_PREFER_{32,64}_BIT_APPS unset
so adjust accordingly. Also clean up an explanatory comment.

GCC know a few pre-defined paths (relative to its location) to
search for headers, libraries, program, etc. By default GCC prefixes
its own path(argv[0]) and calls realpath() which result in absolute
path with all symlink, . and .. removed.
It's usually good to have canonicalised paths, but absolute paths
in *.d file can cause unnecessary relinking when stale entries
in ccache cache hit
Add -no-canonical-prefixes (gcc>=4.6) and
-fno-canonical-system-headers (gcc>4.6) to disable realpath() on
prefixed paths

Now that emulator prebuilts are available under prebuilts/android-emulator/,
disable building the emulator from source in all platform builds, except
if one defines BUILD_EMULATOR to 'true' in its environment.
NOTE: This patch should be applied after this one to avoid issues
with the GPU emulation libraries:

This patch changes the setpaths() function in envsetup.sh to probe
for prebuilts/android-emulator/<host>/, and prepend it to PATH if
it exists.
See https://android-review.googlesource.com/#/c/93399/
for a related patch that adds the binaries.

For a 64bit target, we can have support for both 32bit and 64bit version
binary(like app_process, dalvikvm), and there are some commands like am/pm
will call these commands to implement it's function.
In some targets it will prefer to use the 32bit version, and in other targets
it will prefer to use the 64bit version. So this change is to add the common
work for creating the symlink to the prefer version binary,and avoid the
change on the caller commands side like am/pm.
In this change, it uses TARGET_PREFER_32_BIT_APPS to decide linking to
32bit version or 64bit version.

Some printf/scanf functions in Windows aren't C99 compatible.
Define __USE_MINGW_ANSI_STDIO for mingw compiler to use it's own set of
replacement libraries which are more C99-like.

But not install them.
This prevents "make tests" polluting system.img or userdata.img.
We have new mechanism to build and package up modules into zip file in
build/core/tasks/tools.
Change package-modules.mk to install DATA/ instead of data/ in the
zip file; Better handle of module name conflicting.

With this change, you can package up modules while avoiding installing
them to the system.img or userdata.img.
- build/core/tasks/tools/package-modules.mk
You can use this template to package up modules into a zip file and
preserve the installed file paths.
- LOCAL_PICKUP_FILES, you can use this variable to package up extra
files/directories.

Use LOCAL_LDLIBS to link against prebuilt libraries (such as NDK
libraries).
Previously LOCAL_LDLIBS only applies to host modules and the behaviour
confuses users.
