It will be equally fine if everything installs libraries either into lib64
or into lib32. And then /lib just does not exist.
The problem is that it is not what happens. And while forcing CMake to
comply with /lib is easy, I have no idea how to do that for autotools etc.,
which usually do not have a dedicated portgroup. But if someone can do it
this way, that gonna solve the problem.
