On rerunning my target macro enumeration now it's no longer necessary
to consider libgcc/config/ macros in host-side files, I saw that I'd
missed one remaining DECLARE_LIBRARY_RENAMES definition when poisoning
that macro host-side because of the move to libgcc/config/.  Nathan
Froyd had moved all definitions of that macro to libgcc/config/ on
2010-10-14 - but I'd missed that a definition for Darwin was then
added in gcc/config/ on 2011-02-07.  This patch moves that definition
to libgcc/config/ as well.

Tested building cc1 and xgcc for cross to i686-darwin.  OK to commit?

gcc:
2011-05-10  Joseph Myers  <joseph@codesourcery.com>

	* config.gcc (i[34567]86-*-darwin*, x86_64-*-darwin*): Add
	i386/darwin-lib.h to $libgcc_tm_file.
	* config/i386/darwin.h (DECLARE_LIBRARY_RENAMES): Remove.

libgcc:
2011-05-10  Joseph Myers  <joseph@codesourcery.com>

	* config/i386/darwin-lib.h: New file.
