ARM: detect VFP floating point unit

This sets HAVE_FPU correctly on ARM targets if VFP instructions are
enabled. Note that __VFP_FP__ implies the use of the VFP floating point
format, not the availability of the VFP instructions. Thus software
floating emulation __SOFTFP__ (i.e. gcc -mfloat-abi=soft) is excluded
explicitly.
