Maintaining these two codepaths has practically zero cost, while
forcing every ebuild using qt4-r2 to switch to arrays would waste
developers' time which is better spent elsewhere.
Furthermore, the non-array variant is not necessarily inferior,
because it allows you to use bash globbing, brace expansion, etc...
