add support for module supported or unsupported target architectures Add four new variables for module makefiles: LOCAL_MODULE_TARGET_ARCH specifies that a module is only supported for one or more architectures. Any architecture not in the list will be not attempt to build the module. The expected use case is prebuilts that are only suitable for a single architecture, or modules like llvm that need per-architecture support. LOCAL_MODULE_UNSUPPORTED_TARGET_ARCH specifies that a module cannot be built for one or more architectures. LOCAL_MODULE_TARGET_ARCH_WARN and LOCAL_MODULE_UNSUPPORTED_TARGET_ARCH_WARN are the same, but warn that the arch is not supported, which is useful for modules that are critical but not yet working. The logic for whether or not to build an architecture is fairly complicated, so this patch consolidates it into module_arch_supported.mk Change-Id: I120caf4a375f484e1fd6017b60c2f53882ae01e6

# We don't automatically set up rules to build packages for both
# TARGET_ARCH and TARGET_2ND_ARCH.
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.

# To build it for TARGET_2ND_ARCH in a 64bit product, use "LOCAL_MULTILIB := 32".
Support x86+arm multilib build. Support TARGET_2ND_ARCH as the binary translation arch. See target/board/generic_x86_arm/BoardConfig.mk and target/product/aosp_x86_arm.mk as example for the setup. In BoardConfig, use the TARGET_2ND_ARCH/etc. variables to set up the binary translation arch; Set "TARGET_TRANSLATE_2ND_ARCH := true" to tell the build system it's not a typical 64-bit multilib configuration. In product makefile, use "PRODUCT_PACKAGES += libfoo_<2nd_arch>" to install the TARGET_2ND_ARCH libraries. This also pulls in any dependency libraries. By default we don't install any TARGET_2ND_ARCH modules, unless it's pulled in by PRODUCT_PACKAGES. Bug: 27526885 Change-Id: I0578e9c80da0532d2fa886a8fcdb140bbc703009 (cherry-pick from commit 277e75a488b1b6599482aed9f7c046747baa10df)

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: use TARGET_SUPPORTS_32_BIT_APPS and TARGET_SUPPORTS_64_BIT_APPS Use TARGET_SUPPORTS_32_BIT_APPS and TARGET_SUPPORTS_64_BIT_APPS to determine which native libraries to build for an app. If both are set, it will use 64-bit unless TARGET_PREFER_32_BIT is set. If only one is set, it will only build apps that work on that architecture. If neither is set it will fall back to only building 32-bit apps. On existing 32-bit devices neither variable will be set, and the build system will continue to build 32-bit apps. Once a device has support for a 64-bit runtime, the same logic that selects the dual runtimes should set TARGET_SUPPORTS_32_BIT_APPS and TARGET_SUPPORTS_64_BIT_APPS, and packages will be built for the preferred arch, or fall back to the non-preferrred arch if necessary. For testing, a device may set TARGET_SUPPORTS_64_BIT_APPS without TARGET_SUPPORTS_32_BIT_APPS to produce only 64-bit apps. Change-Id: I5b5e23f15602c3cf9bd96791971208a85492c7a3

Clean common intermediate files if overlay changed This change cleans the packages' intermediate files if their overlays changed between incremental builds. If two builds have different overlay, they will have different R classes, and so the jar files in the common intermediate dirs can not be shared. Therefore incremental build can't be applied. This change detects the overlay changes on package's base. If a package's overlay is different from the previous build, its common intermediate dir is nuked. This makes broader incremental builds possible. Change-Id: I368610ebbbbc85a80f9aecd714ab22cd78da7f12
