The fun begins when the tool tries to use pthread.h assuming it's a regular linux pthread implementation, but ends up using the winpthread's one.

+1 on the general idea. Anything adding $PREFIX/bin to the path during the 
contribs build is wrong/broken, or during the main vlc build itself for 
that matter.

I don't have much else to add on the matter. If you bootstrap two contrib 
build dirs, one native and one for the target, it should be possible to do 
what you want. You'll end up extracting the qt source twice though, but 
aside from that, I think it should work pretty well.

What's missing from contrib today is probably mostly looking for whether 
native build tools are available in $PATH.
