It appears that Apple's gcc-4.2 compilers use __VFP_FP__:

$ gcc-4.2 -x c -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk -dM -E /dev/null | grep -i vfp
#define __VFP_FP__ 1

$ gcc-4.2 -x c -arch armv7 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk -dM -E /dev/null | grep -i vfp
#define __VFP_FP__ 1
