There is a Arm and AArch64 Support section too, is it worth adding a note there either instead or as well? It could maybe just be a note that points back to the Modified Compiler Flags section.

Thanks, I didn't notice that section.

I simplified the note in "Modified Compiler Flags" and added one in "Arm and AArch64 Support".
