Yes, correct.

This is something I already have a patch for in my
codesourcery-toolchain-support branch:

 http://git.buildroot.net/~tpetazzoni/git/buildroot/commit/?h=codesourcery-toolchain-support&id=e6eec872c5720be4438f1d0db28f69ed50620b58

Unfortunately, the changes needed to get the libraries from either /lib
or /usr/lib are mixed with other changes related to multilib support,
and these latter changes are not ready for submission.

I'll try to split the /lib - /usr/lib thing from the rest and submit a
proper patch.

Cheers,

Thomas
