But there always will be people who uses -jN (e.g. me). If we decide
to keep broken PKGBUILD in AUR forever then it means sooner or later
-jN people will be hit by this issues. So the choice is really:

1) Keep the broken packages forever and care only about -j1 people
(who is majority now).
2) Make -jN by default. It will speedup compilation but it also make
the broken packages more visible.

IMHO #2 is better. It is better to highlight all the broken PKGBUILD
and fix it thus make it working for everyone.
