1# We don't automatically set up rules to build executables for both
2# TARGET_ARCH and TARGET_2ND_ARCH.
3# By default, an executable is built for TARGET_ARCH.
4# To build it for TARGET_2ND_ARCH in a 64bit product, use "LOCAL_MULTILIB := 32"
5# To build it for both set LOCAL_MULTILIB := both and specify
6# LOCAL_MODULE_PATH_32 and LOCAL_MODULE_PATH_64 or LOCAL_MODULE_STEM_32 and
7# LOCAL_MODULE_STEM_64
