I am not super happy with having to duplicate all extract and patch
hooks as rsync hooks. The theory is that if you use a
<pkg>_OVERRIDE_SRCDIR, you should know what you're doing, and your
source tree should match the expectations of Buildroot.

But oh well, it kind of makes sense to help in this case, so I've
applied your patch. Still there is an open discussion on where to draw
the line for those post rsync hooks.

Thanks!

Thomas
