Is there a cross-arm-none-eabi-gcc for Tumbleweed?

All, I need cross-arm-none-eabi-gcc for Tumbleweed. I've found community packages, but wonder if there is a Tumbleweed (or slowroll) recommended place to get these packages from. I had planned to convert to slowroll, but the wiki says that may not be advisable if you use repositories that don't provide a slowroll repo. mozilla doesn't, so I'm trying to be careful about where I draw packages from. Any recommendation on where to grab the gcc arm-none-eabi package? -- David C. Rankin, J.D.,P.E.
