    Don't add crtfastmath.o for -shared.

    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.

    [2] https://gcc.gnu.org/pipermail/gcc-patches/2022-December/608529.html

    gcc/ChangeLog:

            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.=
