LGTM. 

Looking at the ARM backend code https://github.com/llvm/llvm-project/blob/main/llvm/lib/Target/ARM/ARMTargetObjectFile.cpp#L46 it does it in a slightly different way, claiming that it can't modify flags on an existing section. It looks like that restriction has been lifted though.

The tests show that it is working and it is simpler to modify, so no objections to doing it that way.
