Follow-up PR with other found licenses:
https://src.fedoraproject.org/rpms/mariadb10.11/pull-request/9

A few of the licenses were not present on Fedora Allowed list and one was on Fedora Not-Allowed list.

Not allowed license resolved via patch that removes the licensed code. Code wasn't previously compiled into the package, this is documented in the PR#9.
