Я разобрался, для чего нужны *.dll.config файлы, и реализовал поиск
soname-зависимостей в *.dll байткоде mono.  Это, в частности, означает,
что теперь mono пакеты, как правило, не могут быть noarch.

Если кто-то разбирается в том, как работает mono на уровне загрузки
разделяемых библиотек, прошу посмотреть нижеследующее и высказаться.


commit 5c616477a2f2fe314d7e684c0e1b75bb85b8f227
Author: Alexey Tourbin <at@altlinux>

    mono.req: implemented MonoLibReq() to grab sonames from *.dll.config files
    
    The idea is that, since Mono bytecode must be portable, it cannot contain
    soname references, only "module references".  Module to soname mapping is
    done with system-dependent *.dll.config xml file.
    
    I grab module references from dll and try to resolve them into sonames.
