Nope, this is expected. During the build output/host/lib doesn't exist,
it's only populated at the very end of the build in host-finalize. So
indeed the RPATH of binaries point to various per-package host/lib
folders. This is totally expected.

This is obviously not good :-)

Thanks for reporting that, I'll have a look. I guess it's simply the
fixup of RPATH from absolute to relative that goes wrong.

Best regards,
