[oe] gcc atomic instruction support for armv5te

[Steffen Sledz]

As mentioned before i try to create a recipe for rsyslog.

Now i hit the next big problem. The last item at
http://www.rsyslog.com/doc-build_from_repo.html says that

"The availability of atomic instructions is vital for rsyslog"

The gcc version 4.3.3 which is used for armv5te by default
misses this. :(

Is there a newer gcc version with atomic instruction for armv5te
machines available/tested? I heard rumors that 4.4.3 shell
have it?
