Hi,

I'm seeing various test suite failures in the 0.158 on various
arches.  I'm currently looing at powerpc since that's the only
Debian release architecture that's having the problem, but I see
it on various non-release arches too.

The test-suite.log file contains:

It seems that for --backtrace-exec it thinks it has support for
unwinding information even when it doesn't and then fails.
