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.
