[PATCH] always override stack-protector variables in EFI build These flags require libc support which we do not have in the EFI part. As distro builders inject the hardening flags into CFLAGS, which is fine for the userspace part, but for EFI we need to override it.
Do not use ld fatal-warnings fatal-warnings are almost guaranteed to break the build when using a more recent linker than the upstream developers. Get rid of them so the package can be built with some warnings and be maintained sanely in the long run.
