Incomplete. My first question is: What project is "fs_variant_partial"
in?

  Although "LLVM ERROR: Cannot select" seems to be from LLVM, I can't
  determine what project "fs_variant_partial" is in. Sounds like it
  might be in some old version of Mesa? The start of the log suggests
  it's running on focal.
