Hey,

Substitute availability is looking pretty good for tex-team now [1], it
seems that for most architectures, it only took ~24 hours to recover
from the rebase.

For i686-linux, bordeaux.guix.gnu.org is slow to catch up due to lack of
hardware, and the machine for powerpc64le-linux is temporarily off at
the moment.

I think tex-team is good to merge.
