There are some known problems in this area which Mentor Graphics ESD
has been fixing and submitting upstream.

They mainly have to do with the graphics and string instructions that
aren't uniformly supported and gcc doesn't know when not to use some
of these instructions.

If your goal is to succeed at compiling things for your target then I
would start here:
http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/platforms/power-gnulinux

or just command-line tools for free, click under "Power Architecture
Processors"->"Download the GNU/Linux release"
http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/editions/lite-edition/

They are all based on the open-source tools but with enhancements to
fix problems like the one you ran into.

I'm part of the team that produces these toolchains so I'm biased :-)

Cheers,
Carlos.
