I just attached the config.log for reference.

This environment is .. Power7, BE.    (i'll see if I can verify that this
does/does not occur in other Power envs shortly.)

willschm@bns:~/gcc/generic.noprereqs.noconfig.debug> head config.log 
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.64.  Invocation command line was

  $ /home/willschm/gcc/trunk.svn/configure --with-cpu=power7
--with-long-double-128 --prefix=/home/willschm/gcc/install/gnc
--disable-bootstrap --enable-languages=c,c++,lto --no-create --no-recursion
