Thanks, committed.

On a related issue, it looks to me that the compiler itself should be
compiled with -funwind-tables, otherwise there are no backtraces
generated, even if libbacktrace is linked in and operational. Again,
x86_64-linux-gnu host defaults to this flag, but other hosts are left
behind.

Uros.
