Cleanup Solaris linker version checks

	* acinclude.m4 (gcc_AC_INITFINI_ARRAY): Don't require
	gcc_SUN_LD_VERSION.
	(gcc_GAS_CHECK_FEATURE): Remove.
	* configure.ac (ld_vers) <*-*-solaris2*>: Move comments from
	gcc_AC_INITFINI_ARRAY here.  Update for Solaris 11.4 changes.
	* configure: Regenerate.
