    arm: 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/arm/linux-eabi.h (ENDFILE_SPEC): Don't add
            crtfastmath.o for -shared.
            * config/arm/unknown-elf.h (STARTFILE_SPEC): Likewise.
