Hello Peter,
Many thanks for your clarifying mail.

I do see the same issue using 2.23.52.20130913 configured --target=ppc64-redhat-linux
and obtained by doing: git clone git://sourceware.org/git/binutils.git I also tried
ftp://sourceware.org/pub/binutils/snapshots/binutils.tar.bz2 (09/13/2013) Would these
be different from the trunk?

Yes, orthogonal to -m<CPU> although, a colleague suggested: --isa-environment
instead.
Thanks again!
