Dear Owen, I'd say the fact that you quickly eat up all your RAM is the best indication for it possibly being a good idea to cross-build for the Odroid on a PC. I've never actually did a cross-compilation for CentOS or Fedora packages (just for the same architecture), but that might just be the way to go: Get a .spec file for GNU Radio on x86_64, adjust it as necessary, and use it to build stuff for the C2. As said, I've never done this myself, though.
