I think on mine the warnings come from the clang to generate bitcode, rather
than gcc. The parallel make output makes that a bit hard to see though, as
commands and warnings are interspersed.

They're all animals for testing older LLVM versions. They're using
pretty old clang versions. phycodurus and dragonet are clang 3.9, petalura and
desmoxytes is clang 4, idiacanthus and pogona are clang 5.
