Mathieu Benoit adc508d8f6 [FIX] python packages: /usr/local, once, for all of them
Debian patches sysconfig to prefer the "posix_local" scheme, so every
wheel-installing PKGBUILD ships /usr/local -- a tree Arch reserves and whose
every path the filesystem package owns. pacman refuses the transaction:

  error: failed to commit transaction (conflicting files)
  /usr/local/share/man exists in both 'filesystem' and 'meson'

Four packages hit it. Two were dropped for other reasons. Rather than write a
third and fourth relocation hook, build_package now exports
DEB_PYTHON_INSTALL_LAYOUT=deb_system, which moves the default from
/usr/local/lib/python3.13/dist-packages to /usr/lib/python3/dist-packages and
scripts from /usr/local/bin to /usr/bin. One line, every python package,
including ones not built yet.

It does not finish the job: deb_system still says dist-packages and Arch reads
site-packages. That move stays per-package, because only modules actually
imported on the target need it. meson does, and its hook does it -- targeting
the version of the python PACKAGE in repo/s390x, not the interpreter running
the build. Installed under the host's 3.13, /usr/bin/meson runs in the chroot
and then says ModuleNotFoundError, because the chroot's python is our 3.14 and
never looks in 3.13.

--- FR ---

Debian modifie sysconfig pour préférer le schéma « posix_local » : tout
PKGBUILD installant une roue livre donc /usr/local, arbre qu'Arch réserve et
dont le paquet filesystem possède chaque chemin. pacman refuse la transaction :

  error: failed to commit transaction (conflicting files)
  /usr/local/share/man exists in both 'filesystem' et 'meson'

Quatre paquets l'ont rencontré. Deux ont été écartés pour d'autres raisons.
Plutôt que d'écrire un troisième et un quatrième crochet de relocalisation,
build_package exporte désormais DEB_PYTHON_INSTALL_LAYOUT=deb_system, qui
déplace le défaut de /usr/local/lib/python3.13/dist-packages vers
/usr/lib/python3/dist-packages, et les scripts de /usr/local/bin vers /usr/bin.
Une ligne, tous les paquets python, y compris ceux pas encore bâtis.

Cela ne termine pas le travail : deb_system dit encore dist-packages quand
Arch lit site-packages. Ce déplacement reste par paquet, car seuls les modules
réellement importés sur la cible en ont besoin. meson en fait partie, et son
crochet le fait — en visant la version du PAQUET python de repo/s390x, non
l'interpréteur qui exécute la compilation. Installé sous le 3.13 de l'hôte,
/usr/bin/meson démarre dans le chroot puis annonce ModuleNotFoundError, le
python du chroot étant notre 3.14, qui ne regarde jamais dans 3.13.
