Yes, that's true. If we encounter anyone trying to build the selftests with <8.1 I think we'll have to add a compiler version test in the Makefile to exclude the static pie tests. There's also the potential issue with arm64 builds that caused the original attempt at -static. We'll likely need an exclusion there too. -- Kees Cook
