If this is a bug fix, what versions of Traffic Control are affected?

The following criteria are ALL met by this PR

• Building the RPMs is the test, no additional tests necessary
• Intended behavior is unchanged, and bug did not exist in the last release, no documentation necessary
• An update to CHANGELOG.md is not necessary
• This PR includes any and all required license headers
• This PR does not include a database migration
• This PR DOES NOT FIX A SERIOUS SECURITY VULNERABILITY (see the Apache Software Foundation's security guidelines for details)

Now that the build's finally finished, I can say that it works.
