Hi,

I'm currently observing the following problem:

$ guix describe
Generation 8    May 24 2022 20:15:17    (current)
  guix 01793ed
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 01793ed03e8aa0960bff7adc21fd270e1527e68e
$ guix uprade
The following packages will be upgraded:
   ...
   gcc-toolchain      11.2.0 → 12.1.0
   ...
guix upgrade: error: gcc-12-strmov-store-file-names.patch: patch not found

As far as I can tell,
https://github.com/guix-mirror/guix/commit/37e29ccd332f371aacedc71388e805fbc9e947fa
added gcc-12, which depends on gcc-12-strmov-store-file-names.patch but
failed to add the file to
https://github.com/guix-mirror/guix/tree/master/gnu/packages/patches, where
the older gcc*-strmov-store-file-names.patch are located.

Regards,
Tim Rakowski
