Grant,
thanks for the pointer!
This is fantastic!  I believe that it would have saved me at least
an hour last Saturday had I known about your page.  Ah well.

It looks like your page is a good reference for building
a "straight" cross-compiler environment.  Building applications
based on glibc that will actually run on the target machine with
Linux as the OS.
What I was trying to do to begin with was a bit simpler - just
build a cross environment to allow code to run on one of the
PPC boards that are available.  No OS yet, certainly not glibc.

What I imagined is having one environment for building the
"simple" environment, and a later one for actually building
the applications to run on Linux with glibc.

Binutils
Originally retrieved from ftp.cygnus.com - but that seems to be a fairly
"old"
version in terms of the PowerPC world.  Downloaded binutils-2.9.1.0.19a
from

ftp://ftp.cdrom.com/pub/linux/tsx-11/packages/GCC/binutils-2.9.1.0.19a.tar.gz

and built and installed it.  Went on to GCC-2.95.2; but it insists that
a
newer
version of binutils is needed.  Referred to binutils-2.9.4.0.8 or newer.
Downloaded
ftp://ftp.varesearch.com/pub/support/hjl/binutils/binutils-2.9.5.0.22.tar.bz2

and will build and install it.

$ cd /usr/local/src
$ bunzip2 -c binutils-2.9.5.0.22.tar.bz2 | tar xf -
$ cd /usr/local/ppc
$ mkdir build-binutils-2.9.5.0.22
$ cd build-binutils-2.9.5.0.22
