arm-linux-gnueabi now provides the atomic builtins; use them
unconditionally (as
libjava does).

Ok for the trunk, if testing succeeds? The build on trunk configured
with
--with-mode=thumb fails for other reasons (PR42093), currently testing
the patch
for the 4.4 branch.

	* include/private/gc_locks.h: For __ARM_EABI__ define
	GC_test_and_set  GC_clear to use the atomic builtins.

OK for trunk once testing is complete.

a test build did suceed without regressions. now that the _sync_synchronise fix is backported to the 4.4 branch, ok to commit to 4.4 branch as well?


Please also notify the upstream maintainer of boehm-gc, or this patch may
get lost in a future merge.

forwarded to Hans Boehm.
