for cross build and disabled NUMA in Arm cross files.

Looking at the original comments in this file, I arrived at the conclusion that this is the documentation about what's supported in an arm cross file. We should have this documented somewhere and this seemed like the best place. It's possible we could mention this in the docs instead. Then the removal of these explanatory comments would make sense.
