Unfortunately this isn't sufficient:
Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong available but compiler is broken
/build/linux-4.9~rc3/Makefile:1069: recipe for target 'prepare-compiler-check' failed
make[5]: *** [prepare-compiler-check] Error 1
scripts/gcc-x86_64-has-stack-protector.sh has its own list of options
which will need to include -fno-PIE.
