build fail with latest 8.1 sources

[John Leo]

Looking more closely at the log output it appears there were some errors or
at least warnings earlier in the output, including for template haskell, so
I've attached the full output.  I'll continue to investigate on my machine,
but again if anyone has pointers I'd appreciate it.  I've build 8.1 many
times and never seen this problem before.
