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.
