building gcc3.02 for ppc405 with Hardhat 2 Journeyman tools

[Dan Kegel <dkegel@ixiacom.com>]

Here's how I built gcc3 and
integrated it into the hardhat tools for ppc405.  Works for me,
but YMMV.  Thanks to Bryan Rittmeyer for the recipe.

#!/bin/sh

set -x -e
WORKDIR=`pwd`

#wget ftp://ftp.gnu.org/pub/gnu/gcc/gcc-3.0.2/gcc-core-3.0.2.tar.gz
#wget ftp://ftp.gnu.org/pub/gnu/gcc/gcc-3.0.2/gcc-g++-3.0.2.tar.gz

# Muck around in the hardhat tree to let the gcc build process find what it
# needs.  FIXME These steps must all be run as root.
cd /opt/hardhat/devkit/ppc/405

# Avoid exit if links exist by using a subshell

ln -s powerpc-hardhat-linux powerpc-linux
cd bin

find . -name crt?.o -exec cp {} powerpc-linux/lib \;

# Extract the source into the same directory as the tarballs
cd $WORKDIR
tar zxvf gcc-core-3.0.2.tar.gz
tar zxvf gcc-g++-3.0.2.tar.gz
