FWIW, I've reverted this patch. It's a feature that already wasn't seen
as very essential, and it's causing some build failures.

I don't think it's really easy to provide a functionality that allows
to build a host executable as a static binary, because most host
systems use glibc, and glibc doesn't officially support static linking.

Feel free to investigate those build failures (see the commit log for
the three different build failures) and send an updated version that
makes sure those build failures are fixed.

Thanks!

Thomas
