There has been already a discussion on this, see 
https://groups.google.com/g/clang-built-linux/c/ayNmi3HoNdY/m/ROdg7avVBwAJ

This apparently is a clang issue. The commit mentionned here is only exposing the issue, but the 
issue is not in the commit itself.

Regardless, this error should go away when we switch to the generic C VDSO.
