devel/llvm37 fails on Intrinsics.gen

[Matthew Pounsett]

I'm building ports using poudriere 3.1.14_2 on FreeBSD 9.3-RELEASE-p43.
 llvm37 3.7.1_3 is failing for me at the following point:

*** [do-build] Error code 1

I first built it with llvm37 listed in ALLOW_MAKE_JOBS_PACKAGES ... that
failed, so I removed it and retried.  The above error is what I got on the
second build.  I've updated my ports tree in case it was a temporary bug in
the port, but that hasn't fixed the problem.

Does this look familiar to anyone?
