I can submit a patch if it is accepted for inclusion.

Update source to hackage instead of github

Change GPL-2.0-or-later to GPL-2.0-only as per https://hackage.haskell.org/package/pandoc-crossref

Add MAINTAINERS.md

I've submitted a patch for review, so I guess this task can be re-opened?

@DataDrake since this issue is in the process of resolving, should I create a separate request for arm-linux-guneabihf gcc toolchain?

Removed redundant %configure

Yes, I'll get to it in couple of days
