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.
