Also give target access to the gnu-user.h LINK_GCC_C_SEQUENCE_SPEC.
In preparation for using gnu-user.h in rs6000/.

Bootstrapped etc. powerpc64le-linux.  OK?

	* config/gnu-user.h (GNU_USER_TARGET_CRTI): Define.
	(GNU_USER_TARGET_STARTFILE_SPEC): Use it here.
	(GNU_USER_TARGET_CRTN): Define.
	(GNU_USER_TARGET_ENDFILE_SPEC): Use it here.
	(GNU_USER_TARGET_LINK_GCC_C_SEQUENCE_SPEC): Define.
