Comment (by gk):

 Okay, I pushed another commit (commit
 570ae84b5182a7d6986e467540318e5282fe0f2e) that fixes the `--enable-tests`
 related problem. It turns out that `fwrapv` does not like the code added
 in https://bugzilla.mozilla.org/show_bug.cgi?id=1432646 and breaks. I have
 not looked closer whether that's a compiler bug or something else. For now
 I just filed an upstream bug
 (https://bugzilla.mozilla.org/show_bug.cgi?id=1514794) and removed the
 `-fwrapv` flag. Which is okayish for our debug build I think.
