Mathieu Benoit a8eef0e460 [FIX] the second half of two of my own hooks
libevent: mv: cannot stat '<pkgdir>/usr/share/doc': No such file or directory
  pam:      rm: cannot remove '.../Linux-PAM/*.pdf': No such file or directory

Both are hooks I wrote in this session, and both stopped a build in exactly the
way this port has documented eight times: the documentation build was disabled
and its install was left in place. Turning EVENT__DOXYGEN off does not stop
package() moving usr/share/doc into the libevent-doc split; -Ddocs=disabled does
not stop pam deleting PDFs it no longer produces.

fakeroot was the first one I made myself. This makes three, so the rule is worth
stating instead of rediscovering: after disabling documentation anywhere, search
package() for share/doc, man, and the split arrays before believing the hook is
finished.

pam's rm becomes tolerant rather than deleted -- on a machine with the DocBook
stack the PDFs are real, and the comment above the line says why they must go:
they are not reproducible.

--- FR ---

  libevent: mv: cannot stat '<pkgdir>/usr/share/doc': No such file or directory
  pam:      rm: cannot remove '.../Linux-PAM/*.pdf': No such file or directory

Deux hooks que j'ai écrits dans cette session, et deux arrêts de construction de
la façon exacte que ce portage a documentée huit fois : la construction de la
documentation désactivée, son installation laissée en place. Éteindre
EVENT__DOXYGEN n'empêche pas package() de déplacer usr/share/doc vers le
sous-paquet libevent-doc ; -Ddocs=disabled n'empêche pas pam de supprimer des PDF
qu'il ne produit plus.

fakeroot fut le premier de ma main. Cela en fait trois : la règle mérite d'être
énoncée plutôt que redécouverte — après avoir désactivé une documentation,
chercher dans package() share/doc, man, et les tableaux de sous-paquets avant de
croire le hook terminé.

Le rm de pam devient tolérant plutôt que supprimé : sur une machine dotée de la
pile DocBook les PDF existent, et le commentaire au-dessus dit pourquoi ils
doivent partir — ils ne sont pas reproductibles.
