# Flatcar: When bootstrapping, we may have a situation where
# CET-enabled gcc from seed is used to build CET-disabled
# glibc. As such, gcc implicitly enables CET if no
# -fcf-protection flag is passed. For a typical package it
# should not be a problem, but for glibc it matters as it is
# dealing with CET in ld.so. So if CET is supposed to be
# disabled for glibc, be explicit about it.
