    sparc: 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.
    
            PR target/55522
            * config/sparc/freebsd.h (ENDFILE_SPEC): Don't add crtfastmath.o
            for -shared.
            * config/sparc/linux.h (ENDFILE_SPEC): Likewise.
            * config/sparc/linux64.h (ENDFILE_SPEC): Likewise.
            * config/sparc/sp-elf.h (ENDFILE_SPEC): Likewise.
            * config/sparc/sp64-elf.h (ENDFILE_SPEC): Likewise.
