До поры до времени.
Начинать готовить адаптацию спека лучше с каких-то достаточно поздних
rc, особенно в случае, когда после выхода времени у мейнтейнера мало, а
чуть раньше — много.

не в рамках одного исходного пакета.

Внимательно посмотрите changelog и архив.

Одна из возможных причин:
http://git.altlinux.org/people/arseny/packages/?p=llvm11.0.git;a=commit;h=4b3c6c13e4d70fd201691c636d57b5b020e00709
Надо думать, что с этим делать.

разве тут что-то неверно?
старый description был слишком неточным и подходил к нескольким бинарным
пакетам.

Я скоро буду собирать пакеты, которые этим будут пользоваться.

Ну, и для "clang -target aarch64-unknown-linux-gnu" какого-нибудь.

man не смотрит в llvm_man1dir.
Заморочиться и научить — вариант хуже, чем текущий, потому что программе
man надо ещё ман от правильной версии достать.
