Простите за offtopic, но пользуясь случаем можно поинтересоваться (я без сарказма, совершенно серьёзно) какие типы символов извлекает lib.req ?

Объясню вопрос: в 2013 я пробовал переписать lib.{req,prov} на libelf и если в случае с prov всё более менее понятно, то с req я смог понять критериев отбора.

lib.req не извлекает символы. Вместо этого он запускает динамический линкер, который составляет полную карту разрешения символов. Чтобы было проще понять, считай, что это исполняемый файл и ты просто запускаешь его через execve c LD_BIND_NOW=1, только в самый последний момент вместо передачи управления в __libc_start_main он печатает карту разрешения символов и выходит.

$ /usr/lib/rpm/ldd --bindings /usr/bin/perl '' 2>&1 | grep /usr/bin/perl
     19804:     binding file /usr/bin/perl [0] to /usr/lib64/libperl-5.22.so [0]: normal symbol `boot_DynaLoader'
...
     19804:     binding file /usr/bin/perl [0] to /lib64/libc.so.6 [0]: normal symbol `exit' [GLIBC_2.2.5]

Дальше этот вывод немного рафинируется и делается join на прилинкованные библиотеки (с которыми слинкован /usr/bin/perl).  Так и получаются set-версионные зависимости.

В общем, с помощью libelf нельзя легко "извлечь" символы, не реализовав при этом чего-то вроде ld.so, который подгружает разделяемые библиотеки и т.д.
