Umm.  I think I know the problem here.  I have a suspicion that either
Fedora or you have changed make to be parallel by default (or you're
lying to me and saying you typed 'make' when you actually typed 'make
-j4', but I'm pretty sure you wouldn't do that).  Because there's no
way you'd get this output if you were compiling with make -j1.

Indeed, if I revert your commit and then build with make -j4, I see the
same error as you.  I'll look at how to fix this properly tomorrow.
