I'm actually hoping that the recent merge of the sysroot branch allows
to avoid this issue, albeit probably not without some adaptation from
gub or the user.  The idea is that you should be passing --with-sysroot
information so that the .la file will have '=/usr/lib' (yes, including
the equals sign) as libdir, and that should fix relinking.

It would be good if somebody could verify this to be the case; I do not
currently have the resources to try out gub.

Cheers,
Ralf
