GCC behavior regarding defining __SOFTFP__ when (implicitly) specifying
-mfloat-abi=softfp:

- compile without (implicit) FP: define __SOFTFP__
- compile with (implicit) FP: don't define __SOFTFP__

Currently Clang doesn't define __SOFTFP__ when softfp is specified, either with
or without FP. This patch brings Clang in line with GCC behavior.
