I'm travelling at the moment, so basic troubleshooting is going to be
a bit delayed, just as a quick status report, I'm getting linker
failures in some of the tests.  I've checked that nptl/libpthread.so
has _Unwind_Resume in it, so I'll need to do more hunting this week.

Error message follows in case someone has an obvious "aha":
