Since we switched to $(HOST_OUT)/lib64 for 64-bit libraries and
$(HOST_OUT)/lib for 32-bit libraries.

We first define TARGET_COPY_OUT_VENDOR as a placeholder. In product
config makefiiles we actually get the placeholders in
PRODUCT_COPY_FILES. A device can set up TARGET_COPY_OUT_VENDOR in its
BoardConfig.mk. We substitute the placeholder with the real
TARGET_COPY_OUT_VENDOR value after loading the BoardConfig.mk.
With this change, we can support building vendor stuff to
system.img (the default) or a separate vendor.img.

Set up TARGET_IS_64_BIT and HOST_IS_64_BIT early so we don't need 2
mechanisms to judge if it's 64-bit build;
Remove the unnecessary 32-bit host variables.

In 64-bit multilib host build, changed from
32-bit lib: out/host/<platform>/lib32
64-bit lib: out/host/<platform>/lib
to
32-bit lib: out/host/<platform>/lib
64-bit lib: out/host/<platform>/lib64
.
That way the host library path is consistent with the multilib target
build's. Also with this change prebuilt 32-bit libraries can be reused
in 64-bit host build as 2nd arch binaries. (With previous setup, they
can't be used because they have rpath ../lib in it while the 2nd arch
library path needs ../lib32.

With multilib host build, the build system installs host
shared libraries to different directories depending on a
library's bitness:
- HOST_OUT_SHARED_LIBRARIES points to the library path of 64-bit;
- 2ND_HOST_OUT_SHARED_LIBRARIES points to the library path of 32-bit;
- If you don't care the bitness of the libraries and just want whatever
version the librareies are built by default, use HOST_LIBRARY_PATH.

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.

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.

To build oem.img:
- You must define BOARD_OEMIMAGE_PARTITION_SIZE in your BoardConfig.mk
- The file system type will be the same as system.img and userdata.img.
- To install a module to oem.img, use "LOCAL_OEM_MODULE := true"
- run "make -j48 showcommands oem_image dist". By default it's not
built.

Introduce ro.product.cpu.abilist32 / abilist64, which are
comma separated lists of the 32 and 64 bit ABIs that the
device supports. These properties are used by the zygote and
system server to determine what ABI an app should be
started with.
This changes move abilist related make steps out of envsetup.mk
and into config.mk because they depend on variables set by
core/combo/***. Additionally, config.mk performs a few additional
cleanups of these variables (like stripping them) after the
inclusion of envsetup.mk so this seems like a better place to
put them.

Add a (read only) system property that is a comma
separated list of ABIs supported by the device in order
of preference. For example, typical arm-v8 device might
define:
ro.cpu.abilist = arm64-v8a,armeabi-v7a,armeabi
For most purposes, a single flattened list like the above is
probably more useful than the parallel system of variables
TARGET_CPU_ABI{2} / TARGET_2ND_ARCH_CPU_ABI{2} that we use
in the build system.

* commit '8c89a9ff9cd461e4bc077a91a0c7c32b17a92ebd':
add new gen/ directory for generated sources
warn on LOCAL_MODULE_PATH in multiarch shared libraries
Support LOCAL_MODULE_RELATIVE_PATH
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.

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.

Now we have a phony target "tests" instead.
The target can be built in any other build variant (eg userdebug).
For example, "make PRODUCT-full-userdebug tests dist" will build and
put the *-test-* zip file in the dist dir.
The "tests" target will include all modules tagged as "tests" in
addition to other modules in specific target out directories.
