Always run LTO tests on Linux with GCC 4.9 or newer

Check for LTO availability will hide LTO bugs in ld.  Since GCC 4.9 adds
-ffat-lto-objects, we always run LTO tests on Linux with GCC 4.9 or newer.

	* testsuite/lib/ld-lib.exp (check_lto_available): Return 1 on
	Linux with GCC 4.9 or newer.
	(check_lto_fat_available): Likewise.
	(check_lto_shared_available): Likewise.
