These two tests currently fail if using gold, in the first instance
because powerpc64 gold doesn't support mixing old dot-sym objects
with new objects, and in the second instance because gold doesn't have
a --no-toc-sort option.  Both macros ought to be defined for gold.
Tested etc.  OK to apply everywhere?

	* configure.ac (HAVE_LD_NO_DOT_SYMS): Set if using gold.
	(HAVE_LD_LARGE_TOC): Likewise.
	* configure: Regenerate.
