Commit Message
Patches [1] and [2] fixed PR55522 for x86-linux but left all other x86
targets unfixed (x86-cygwin, x86-darwin and x86-mingw32).
This patch applies a similar change to other specs using crtfastmath.o.
Ok for trunk?

PR target/55522
* config/i386/cygwin.h (ENDFILE_SPEC): Link crtfastmath.o
whenever -mdaz-ftz is specified. Don't link crtfastmath.o when
-share or -mno-daz-ftz is specified.
* config/i386/darwin.h (ENDFILE_SPEC): Ditto.
* config/i386/mingw32.h (ENDFILE_SPEC): Ditto.

The patches in [1],[2] are already approved, and these 2 patches just
apply them to other 3 targets, so I assume it should be ok, and i'm
going to push the patch to trunk.
