So, since these could be deleted with -f nothing was depending on them
any more, which means at least that the build infrastructure did the
right thing. And probably through the magic of bl3 the xscreensaver is
correctly compiled against only -5's libs, so the only thing wrong was
that the old libs were confusing the dynamic linker.

However: should it be steam_roller's responsibility to remove packages
that are marked for rebuild and are found to no longer be appropriate
for the current platform? If not, what should be done so this
situation gets handled automatically next time?
