Hi echristo, grosbach,
ARMv7 chipsets usually are paired with a NEON FPU. However, this is not
required (e.g. tegra2). Rather than always forcing NEON as the FPU for ARMv7
chips, honour the -mfpu flag, which already is being done. If -mfpu is not
specified, then let the default FPU remain selected (VFP).
