Core updates frozen.

[Mathieu Othacehe]

Hello,

A new core-updates-frozen branch is available here:
https://git.savannah.gnu.org/cgit/guix.git/log/?h=core-updates-frozen.

This means that the core-updates branch remains open, while the
core-updates-frozen branch will only accept bug fixes.

This branch contains exciting new features, such as:

* Switch to GCC 10.
* Update to TexLive 2021.
* Simplified package inputs[1].
* Build system Gexp support[2].
* Meson cross-compilation support[3].

between lots of other things.

Cuirass has started evaluating this branch here:
https://ci.guix.gnu.org/jobset/core-updates-frozen. According to the
related dashboard, there's still a bit of work required to stabilize
this branch: https://ci.guix.gnu.org/eval/68124/dashboard.

Your help is welcome :).

Thanks,

Mathieu
