I can't think offhand of any reason why it's important to have PR
available at parse time, but if that's the case then you could splice it
into DISTRO_PR (or some equivalent variable) instead.

My reference to PV above was spurious; it's no different to PR in this
context.  If you want parallel installation then it's actually PKG_xx
that you need to modify (or, conceptually, PN, but fiddling with that
would almost certainly be a bad idea).
