Description of problem:

When installing ruby-devel in a very minimal env (example, a container for openshift), it seems that building a compiled gem requires gcc, and rpm-redhat-config, or it fail with a weird error.

That's kinda similar to what happened with python:
https://bugzilla.redhat.com/show_bug.cgi?id=1496757

And the fix:
https://src.fedoraproject.org/rpms/python3/pull-request/15

Would it make sense

Version-Release number of selected component (if applicable):


How reproducible:
each time

Steps to Reproduce:
1. make a docker container from F27 
2. install ruby-devel and gcc inside
3. try gem install asciibinder (for example)

Actual results:

it fail with a error related to the rpm-config

Expected results:

it shouldn't fail on that.
