Below, I've attached a patch for pkgsrc/mk/bsd.pkg.subdir.mk which
implements a new target 'fastclean'. This could of course replace the
'clean' target instead, if appropriate.

current clean target from toplevel
497.330u 218.665s 12:56.43 92.2%        0+0k 6112+7401io 117pf+0wo
fastclean with Skipping (patch below) from toplevel
3.397u 2.219s 0:36.31 15.4%     0+0k 4848+80io 0pf+0w
fastclean quietly (patch below, minus 'Skipping' echo) from toplevel
3.287u 1.815s 0:35.89 14.1%     0+0k 4848+80io 0pf+0w

So, 13 minutes before, and 36 seconds using this patch. I tried taking
out the 'Skipping' echo, since I thought output overhead might be
getting significant, but it didn't matter much. Personally, I prefer the
cleaner (hah) output though.

If there's no discussion, I'll talk to the pkgsrc infrastructure people
about applying some form of this.
