I'd suggest to actually more the PKGBASE define to bsd.prefs.mk and add
a modifier variable for the final (full) name. I believe this captures
the interesting use cases better than the current usage.

So basically we have PKGBASE_OPTION_MODIFER or so, that can be set
later, but e.g. PKGBASE and PKGBASE_NOREV are already defined. I still
expect some breakage, but it should be possible to sort that out.
