I'm afraid I really don't like this. Its creating a twisted web of
logic which is going to be hard to maintain as the code is trying to do
too many different things.

In particular, hardcoding "lib64" is usually a bad sign, as is swapping
/lib for nonarch_base_libdir since whilst those happen to be similar,
they do mean different things here. Its pure luck that usrmerge happens
to end up doing the right thing and it will work until someone else
wants to do something interesting with the layout and we can complicate
this even more.

I'm hoping there is a better way to address this...

Cheers,

Richard
