Add Android ARMEABI_V7A_HARD for Hardfp support
Add Android HardFP support. Expose the "armeabi-v7a-hard with NEON" ANDROID_ABI. TEST= Add -DANDROID_NATIVE_API_LEVEL=21 -DANDROID_ABI="armeabi-v7a-hard with NEON" to compile with hardfp. Checked the output of make verbose to confirm -lm_hard is being linked. There are known test failures but that can be fixed once this is in.
