For the record, this was my bug report. I noticed it when using the
chroot tools, which check the return status from makepkg. In essence,
the scripts only move packages and things if makepkg succeeds.

I have since changed the chroot scripts to always check for the
existence of a pkg.tar.gz after build, regardless out output, but this
is still an iffy case: what if tar fails in the middle of making the
file, and doesn't delete the goofed file? makepkg would probably
notice. So the return status is nice to know, and it should really
only be if "make package" makes a package or not
