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.

Build system support to export include paths Bug: 5573756 With this change, we can set LOCAL_EXPORT_C_INCLUDE_DIRS in the module definition to export include dir paths. Paths in LOCAL_EXPORT_C_INCLUDE_DIRS should be relative to the top dir of the source tree. If a library (shared or static) exports some include paths, any module using it will import the include paths and add them to the compiler command line.

Build from source or prebuilt With this change, you can easily switch between building from source code and prebuilt. Set LOCAL_PREBUILT_MODULE_FILE to the path of the prebuilt file, relative to the top of the source tree, in the usual module definition. The prebuilt will be used unless any of the followings satisfied: 1) ANDROID_BUILD_FROM_SOURCE is "true", which disable prebuilt globally; 2) The module name is in ANDROID_NO_PREBUILT_MODULES; 3) The LOCAL_PATH is prefixed by any of ANDROID_NO_PREBUILT_PATHS. A developer can set ANDROID_NO_PREBUILT_MODULES or ANDROID_NO_PREBUILT_PATHS to build only his own module(s) from source, while build other modules from prebuilts. You can set ANDROID_BUILD_FROM_SOURCE to true to build everything from source. Those variables can be set with shell environmental variable or in your buildspec.mk. Sometimes module B is able to be built from source only if module A is also built from source, for example, if B is the test apk of A. In that case, you can use the macro include-if-build-from-source to include B's Android.mk only if A is built from source too, or if-build-from-source to conditionally include the definition of module B, if their module definitions are in the same Android.mk. Support host-executable-hook and host-shared-library-hook. Change-Id: Icab7cf028c87eaba0dd7efc2a7749fd6f32b44e4
