improve macro logic for enabling arm math asm
in order to take advantage of the fpu in -mfloat-abi=softfp mode, the __VFP_FP__ (presence of vfp fpu) was checked instead of checking for __ARM_PCS_VFP (hardfloat EABI variant). however, the latter macro is the one that's actually specified by the ABI documents rather than being compiler-specific, and should also be checked in case __VFP_FP__ is not defined on some compilers or some configurations.
