Change default -mfpu type to 'vfpv3d16' instead of 'vfp'
'vfp' really corresponds to VFPv2, with 'vfpv3-d16' corresponding
to the mandated minimum FPU architecture for ARMv7-A and hence
armeabi-v7a.
Note that 'vfpv3-d16' adds a few instructions on top of 'vfp' which
relate to loading a small set of immediate values directly into
FPU registers (e.g. +1.0, -1.0, etc). Any code that was previously
generated with -mfpu=vfp will still work, and any code that targets
'vfpv3d16' will work on all armeabi-v7a capable devices.
For more information, see the documentation comments in
sources/android/cpu-features.c introduced in this patch:
