Darwin: Section anchors must be linker-visible.

In principle, these begin (or at least delineate) a region that
could be split by the static linker.  If the symbols are hidden
to newer linkers they produce diagnostics about the temporary
symbol generated.

gcc/ChangeLog:

	* config/darwin.h (ASM_GENERATE_INTERNAL_LABEL): New
	entry for LANCHOR.
