Subject: cmake: fix detection of CPUs

Patch-mainline: yes

Git-commit: 82ab993cbbe17c71ca20c4af7b1a4b6f9fa95c45

References: build fix

​

The code defines a function foo returning int, but contains no return.

So the detection fails with "CPU not supported". As new gccs warng abotu

missing return, it causes the detaction to fail. Switch foo to return

void.
