PATCH: Handle atomicity.h configuration for FreeBSD

[Loren James Rittle]

This patch gets us back to where we were before the grand atomicity.h
reorganization.  Since FreeBSD is not currently bootstrapping against
libstdc++-v3, I can only report that this patch at least now allows
libstdc++-v3/configure --enable-threads\=posix to run without error
and configures our target as it did before the recent reorganization.

	* acinclude.m4 (GLIBCPP_ENABLE_ATOMICITY): Handle FreeBSD.
	* aclocal.m4, configure: Rebuilt.
