As you guys don't want Gentooish attempts to check if gcc is compiling the
kernel, what about making/requesting a wrapper that calls gcc with the
appropriate options (-fno-PIE and whatever is needed for fstack protector)?

This would require manually appending CC=the-wrapper to make but would allow
bisects. And come on, any solution with no bisects is rather ridiculous.
