[Qemu-trivial] [PATCH] softfloat: Reinstate accidentally disabled target-specific NaN handling

[Peter Maydell]

Include config.h in softfloat.c, so that the target specific ifdefs in
softfloat-specialize.h are evaluated correctly. This was accidentally
broken in commit 789ec7ce2 when config-target.h was removed from
softfloat.h, and means that most targets will have been returning the
wrong results for calculations involving NaNs.
