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.

	PR target/55522
	* 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.
	* config/aarch64/aarch64-linux.h (GNU_USER_TARGET_MATHFILE_SPEC):
