Libtool has a problem with this.

I know how to work around this in some of the cases, using -rpath-link),
and/or messing around with the staged .la files.

I have no idea how to fix this issue in libtool in a more or less
general way, for anything but the GNU binutils linkers and maybe the
Solaris linker (haven't checked).  That this isn't fixed for binutils
yet, has practical reasons, for which there is at least a tiny chance
of becoming less of a problem in the near future.  That said, even for
binutils I am not yet sure we can fix the general case fully
deterministically.

ACK.

The libtool/tests/destdir.at file shows what currently works, and on
which systems it works.  If you provide a further example that should
work, then we can base that for tests when we do fix things.

Hope that helps.

Cheers,
