[PATCH 3/9] arm: Don't add crtfastmath.o for -shared

[Richard Biener via Gcc-patches]

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

        PR target/55522
        * config/arm/linux-eabi.h (ENDFILE_SPEC): Don't add
        crtfastmath.o for -shared.
        * config/arm/unknown-elf.h (STARTFILE_SPEC): Likewise.
