A simple solution to that is to set the env var in a Q_CONSTRUCTOR_FUNCTION :

void hackXdgDataDirs()
{
   qputenv("XDG_DATA_DIRS", "somevalue");
}
Q_CONSTRUCTOR_FUNCTION(hackXdgDataDirs)

This will run before main().
Whether it runs before the other things that run before main, like KCatalog,
that's less sure. YMMV.

Note: this is just a reply to "how to set something before main()",
it might not be the best solution overall to this problem, dunno.
