flag-o-matic.eclass: drop -fstack-check from ALLOWED_FLAGS (strip-flags whitelist) -fstack-check is _not_ a safe flag: * https://developers.redhat.com/blog/2017/09/25/stack-clash-mitigation-gcc-background * https://developers.redhat.com/blog/2019/04/30/stack-clash-mitigation-in-gcc-why-fstack-check-is-not-the-answer Nobody is really interested in maintaining this functionality upstream in GCC anymore for this reason, it's not IIRC supported in Clang, and we're not testing it either. Please use the far superior -fstack-clash-protection instead.
