add lto to powerpc-*darwin and enable for 32bit darwin

Steven Bosscher  <steven@gcc.gnu.org>
ChangeLog:
	* configure.ac (--enable-lto): All *-apple-darwin* now support LTO.
	* configure: Regenerate.

gcc/ChangeLog:
	* config.gcc (powerpc-*-darwin*, powerpc64-*-darwin*): Add
	lto-macho as lto_binary_reader.

	* darwin.c (darwin_asm_named_section): Do not add assembler comment
	after .section directive; just print it before the directive instead.
