PATCH: ld/1485: --enable-targets=all doesn't work for 64bit target


This patch checks 64bit bfd properly so that --enable-targets=all will
work for 64bit target and host.

	PR ld/1485
	* configure.in: Use ${srcdir}/../bfd/config.bfd to check 64bit
	bfd.  Support 64bit host for --enable-targets=all.
	* configure: Regenerated.
