x86: Don't add crtfastmath.o for -shared
Don't add crtfastmath.o for -shared to avoid changing the MXCSR register
when loading a shared library. crtfastmath.o will be used only when
building executables.
PR target/55522
* config/i386/gnu-user-common.h (GNU_USER_TARGET_MATHFILE_SPEC):
Don't add crtfastmath.o for -shared.
* doc/invoke.texi (-shared): Add related documentation.
