Subject: Tell Soong about HOST_CROSS_*
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d6e3b841850d9a607eb9c841d9fa1836feedee5f;p=android-x86%2Fbuild.git

Tell Soong about HOST_CROSS_*

This configures Soong to build windows binaries, which requires support
for 64-bit windows binaries in BUILD_PREBUILT for USE_SOONG=true.

module_arch_supported.mk did not support 64-bit being the secondary
architecture when evaluating multilib conditionals. All other uses of
HOST_*_IS_64_BIT already check the proper version.
