linux-libc-headers фактически obsoleted by glibc-kernheaders. Он не
обновляется уже более года. Может проставим соответсвующие
Obsoletes/Provides в glibc-kernheaders и выкиним linux-libc-headers?
Конечно, хорошо бы после этого сделать тестовую пересбоку.

linux-libc-header есть в BuildRequires следующих SRPM'ок:
