How would this fit in the logic where IIUC you just remove '_64' from 'x86_64' to get 'x86'
Huh? That's not what tools/scripts/Makefile.arch does.
Hum ... yes sorry I looked at it too quickly and mixed things up with the other patch.
Nevertheless, if I understand well what tools/scripts/Makefile.arch does on an x86_64 for instance:
uname -m returns x86_64 HOSTARCH = x86 (sed -e s/x86_64/x86) ARCH = x86 SRCARCH = x86
If you build with make ARCH=x86_64, SRCARCH = x86
So I still can't see how you can use that to know if it is a x86_64 or not.
By the use of CONFIG_X86_32, which is also used elsewhere in that samme makefile for something else (so I assume it's wired up in the context where it counts, and if not, that's a bug that affects both spots and should be fixed)..
