[Bug bootstrap/40221] New: Powerpc bootstrap is broken in building libstdc++

[meissner at linux dot vnet dot ibm dot com]

I was testing my patch for 40219, and I rebuilt today's build on the Powerpc,
and had the build fail in building libstdc++-v3.  I backed out my change, and
redid the build, and I get exactly the same failure:

Given where it occurs, I suspect it is due to this change:

        * include/tr1_impl/functional (function): Use explicit operator bool.
