    aarch64: Don't add crtfastmath.o for -shared
    
    Don't add crtfastmath.o for -shared to avoid altering the FP
    environment when loading a shared library.

            * config/aarch64/aarch64-elf-raw.h (ENDFILE_SPEC): Don't add
            crtfastmath.o for -shared.
            * config/aarch64/aarch64-freebsd.h (GNU_USER_TARGET_MATHFILE_SPEC):
            Likewise.
