It's important to note that those warnings never show up on their own. They
are only printed in case there is something else the compiler warns about
(libnl header issue covered by gentoo bug #366561 in this case).

Yes, this warning present in gentoo libnl-1.1-r2 and patch doesn't present in gentoo main tree.
I will try to contact with gentoo maintainer and ask to make "some activity".

And I
remember seeing it since these gcc options were introduced several releases
ago.

This option present in gcc 4.5.3 (i made test on hello world). No warning about unrecognized params with
another files. Also, other files compile without warning. You can see it on this part of log: http://pastebin.com/wPnLJ1Fx (verbose build mode)
I think, this is not problem of libvirt
