Which are fixes to QSP's implementation on those platforms, and doesn't 
require new APIs or hooks/backdoors.

I'd like to see these unmodified Unix libraries and shared resources, 
and in which case having XDG variables helps. For non-framework 
libraries perhaps an extensions to QLibraryInfo that lets the library 
figure out its own install prefix is more appropriate. We also already 
have a cross platform solution for library resources: QRC, so some of 
these use-cases may be better supported by that.
