Ok, thanks for the info.  I'm a bit unclear on how the parallelization
stuff in share/ actually works, but I'm happy to help crowbar at things.

Yeah.  To be honest, it's the similar situation I emailed you privately
about a few weeks ago with the race in rescue/ that makes no sense.  So
while I don't entirely trust make(1) reporting what blew up, unlike the
issue in rescue/, the 'NAME is mandatory' error has been about 90%
reproducible between both amd64 and i386.  (Without being able to build
at least amd64, I cannot test other architectures.  Useless data point,
I know.)

48.
