## Standard rules for copying files that are prebuilt

## Additional inputs from base_rules.make:
## None.
add feature to strip "# comment" lines from prebuilt files Change things so that when $(LOCAL_PREBUILT_STRIP_COMMENTS) is nonempty, we copy the source file using sed to strip out all the "# line"-style comments and blank lines, saving considerable system image space in the case of some wifi configurations.

Fix OVERRIDE_BUILT_MODULE_PATH for prebuilt shared libraries. So that prebuilt shared libraries can be referenced with the module name in other module's Android.mk. Change-Id: I4c4b471696642694b805b71dd7605b91724ad924

ifdef LOCAL_IS_HOST_MODULE
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.

add support for LOCAL_MULTILIB LOCAL_MULTILIB replaces LOCAL_32_BIT_ONLY and LOCAL_NO_2ND_ARCH, although both are still supported. Set LOCAL_MULTILIB := 32 to always build a module 32-bit. This is the same as specifying LOCAL_32_BIT_ONLY. Set LOCAL_MULTILIB := first to always build a module for the first architecture (64-bit on a 64-bit target, 32-bit on a 32-bit target). This is the same as specifying LOCAL_NO_2ND_ARCH. Set LOCAL_MULTILIB := both to build for both architectures on a mulitlib (64-bit) target. If LOCAL_MULTILIB is not set libraries will default to "both", and executables, packages, and prebuilts will default to building for the first architecture if supported by the module, otherwise the second. Executables that set LOCAL_MULTILIB := both must set either LOCAL_MODULE_STEM_32 and LOCAL_MODULE_STEM_64 or LOCAL_MODULE_PATH_32 and LOCAL_MODULE_PATH_64 to specify how to differentiate the install locations of the two versions.
