b29ac89e7a [FIX] trust artefacts, not exit codes; add a PKGBUILD patch mechanism
A run reported "51 built, 0 failed" while glibc, gcc, coreutils and
pacman had all failed. The cause is a bash rule that is easy to forget:
callers invoke build_package inside an "if", and "if" DISABLES set -e
for the whole function body. A failing makepkg fell through to
repo-add, whose success became the function exit status.

build_package now returns explicitly on failure and, more importantly,
verifies that a package file actually exists. An exit code is not
proof; only the artefact is. Measured before the fix: 23 files in the
repository where a hundred were claimed.

First real port patch, applied through a per-package hook rather than
by hand: the glibc PKGBUILD passes --enable-sframe, and s390x has no
SFrame at all -- configure refuses outright. Hooks re-clone cleanly, so
an upstream change is never silently discarded.

--nocheck for stage 1: these test suites run against the HOST
libraries, not the Arch ones, so their verdict says nothing about the
port. acl failed its check step on a sound build. Stage 2 runs them for
real.

The remaining failures were host makedepends that --nodeps hides: po4a,
gnat, debuginfod and jansson are now installed up front.

Une execution annoncait « 51 built, 0 failed » alors que glibc, gcc,
coreutils et pacman avaient tous echoue. La cause est une regle de bash
qu on oublie : build_package est appelee dans un « if », et « if »
DESACTIVE set -e pour tout le corps de la fonction. Un makepkg en echec
poursuivait jusqu a repo-add, dont la reussite devenait le code de
sortie.

build_package rend desormais la main explicitement en cas d echec et,
surtout, verifie qu un fichier de paquet existe vraiment. Un code de
sortie ne prouve rien ; seul l artefact prouve. Mesure avant
correction : 23 fichiers dans le depot la ou cent etaient annonces.

Premier vrai correctif de portage, applique par crochet et non a la
main : le PKGBUILD de glibc passe --enable-sframe, et s390x n a aucun
SFrame -- configure refuse net. Les crochets survivent a un reclonage,
donc une evolution amont n est jamais perdue en silence.

--nocheck pour l etage 1 : ces suites s executent contre les
bibliotheques de l HOTE, pas celles d Arch, et leur verdict ne dit rien
du portage. acl echouait a son etape check sur une compilation saine.
L etage 2 les executera pour de vrai.

Les autres echecs etaient des makedepends d hote que --nodeps masque :
po4a, gnat, debuginfod et jansson sont poses d entree.

1a0e19a368 [ADD] stage 1: build a self-hosting core for s390x
Forty-odd packages in link-time order, from linux-api-headers to
pacman itself. The order follows what a compiler actually needs, not
pacman metadata: --nodeps means nothing is ever checked, so anything
required at link time has to exist already.

A failure does not stop the run. One missing package must not hide the
state of the forty that follow, so failures are collected and reported
at the end, each with its own log. A state file makes the run
resumable, which matters when a single gcc build is measured in tens
of minutes.

The header states why stage 1 is not the port: everything here links
against the host glibc, because Arch glibc needs an Arch gcc which
needs an Arch glibc. Stages 2 and 3 break that circle.

bootstrap-pacman.sh now guards its own main so it can be sourced for
build_package without re-running the whole bootstrap.

--- FR ---

Une quarantaine de paquets dans l ordre des dependances de lien, de
linux-api-headers a pacman lui-meme. L ordre suit ce dont un
compilateur a reellement besoin, pas les metadonnees de pacman :
--nodeps ne verifie jamais rien, donc tout ce qui sert au lien doit
deja exister.

Un echec n arrete pas la course. Un paquet manquant ne doit pas
masquer l etat des quarante suivants : les echecs sont collectes et
rapportes a la fin, chacun avec son journal. Un fichier d etat rend la
reprise possible, ce qui compte quand un seul gcc se compte en
dizaines de minutes.

L en-tete dit pourquoi l etage 1 n est pas le portage : tout s y lie a
la glibc de l hote, parce que la glibc d Arch reclame un gcc d Arch
qui reclame une glibc d Arch. Les etages 2 et 3 brisent ce cercle.

bootstrap-pacman.sh garde desormais son main pour etre sourcable et
fournir build_package sans relancer tout l amorcage.

057b1b471c [ADD] bootstrap pacman, makepkg and repo-add natively on s390x
The README lists pacman, bash and coreutils as three missing pieces.
They are not three tasks: pacman is the only one that matters, because
its source tree also ships makepkg and repo-add. Once those run, every
remaining package stops being hand-work and becomes makepkg on the
upstream PKGBUILD.

pacman 7.1.0 builds unpatched on s390x. No cross-compilation is
involved: on native hardware the whole userspace builds at full speed,
which removes the z/VM round-trip the other scripts need.

Measured end to end: zlib built from the official PKGBUILD yields
zlib, zlib-static and minizip, all tagged arch = s390x, the library
reporting "ELF 64-bit MSB shared object, IBM S/390", and repo-add
indexing them into a usable core.db.

--- FR ---

Le README annonce pacman, bash et coreutils comme trois pieces
manquantes. Ce ne sont pas trois travaux : seul pacman compte, parce
que son arbre source livre aussi makepkg et repo-add. Des qu ils
tournent, chaque paquet restant cesse d etre du travail manuel et
devient un makepkg sur le PKGBUILD amont.

pacman 7.1.0 se compile sans correctif sur s390x. Aucune compilation
croisee n intervient : sur du materiel natif tout l espace utilisateur
se batit a pleine vitesse, ce qui supprime l aller-retour z/VM dont
dependent les autres scripts.

Mesure de bout en bout : zlib bati depuis le PKGBUILD officiel produit
zlib, zlib-static et minizip, tous marques arch = s390x, la
bibliotheque se declarant « ELF 64-bit MSB shared object, IBM S/390 »,
et repo-add les indexant dans un core.db utilisable.
