[PATCH, i386]: Do not compile crtfastmath.c and crtprec.c for soft-float targets

[Uros Bizjak]

Hello!

There is no point to access FP hardware for soft-float targets.

2013-11-03  Uros Bizjak  <ubiz...@gmail.com>

    * config/i386/crtfastmath.c: Compile only for !_SOFT_FLOAT.
    * config/i386/crtprec.c: Ditto.

Tested on x86_64-pc-linux-gnu, committed to mainline SVN.

Uros.
