Dwarf unwind test failures on various arches

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:
   elfutils 0.158: tests/test-suite.log

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