When we have shared libraries linked with shared libraries in the same
build tree, this won't work either.

On a number of systems, a library gets encoded in itself the path to
find the libraries it depends on.  For example, libgcj depends on
libstdc++ (say) depends on libgcc_s: this means libstdc++ is created
such that it knows where libgcc_s is installed, and libgcj knows where
libstdc++ is installed.  We just can't install them elsewhere and
expect things to work.

I don't see why it would be more robust.  It's just doing with
libgloss what we already do with newlib and libstdc++-v3.  I don't
want any drastic changes in the build infrastructure this close to a
release.
