We have determined that we can bypass the failure with the following configure
switches:

--with-long-double-128 --with-cpu-32=power4 --with-tune-32=power6
--with-cpu-64=power4 --with-tune-64=power6

This binutils email thread may be relevant:

The assembler that we're using is based on binutils 2.20.51.0.2 which is circa
the July, 2010 time frame.
