Yes, that would be ideal. My microblaze assembler isn't up to it, though :-(
Where do I add the check?
All the work is done in libc/string/Makefile.in to select the generic version
or the arch-specific version. Surely we don't want anything
arch-specific in there.
So where?
In config.in, either the generic one or the arch specific one.
