Michal Kubecek c93db682cf kbuild: dummy-tools: adjust to stricter stackprotector check ...

Commit 3fb0fdb3bb ("x86/stackprotector/32: Make the canary into a regular
percpu variable") modified the stackprotector check on 32-bit x86 to check
if gcc supports using %fs as canary. Adjust dummy-tools gcc script to pass
this new test by returning "%fs" rather than "%gs" if it detects
-mstack-protector-guard-reg=fs on command line.
