Hi Eric,

I'm having trouble building the python2 package on core-updates (which
was renamed from core-updates-next), and I think it relates to this
change.

This is roughly the issue I'm seeing:

  LD_LIBRARY_PATH=/tmp/guix-build-python2-2.7.15.drv-0/Python-2.7.15 ./python 
-Wd -3 -E -tt  ./Lib/test/regrtest.py -l -j12

  -l and -j don't go together!


Since all the python packages look to inherit from python-2.7 that's
being changed here, perhaps this worked for some of them (I know you
mentioned python-minimal in one message), but not all of them, or at
least python2?

Thanks,

Chris
