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.

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.
