Here's an updated script (still rough) to build binutils, gcc, and
newlib

The trick was that you should never, never, never build gcc within it's
own directory. I remembered that from some other gcc work I'd done a
while back and it holds true. The problem is that weird things creep in
from some hacks within the gcc build process. I think the 3.x series is
ok, but the 2.x series was prone to these little issues creeping in.
I've both cat'ed the script into the text here and mime-attached it.
There is still an error thrown about not having libxil.a, but this
should cure all of the other ills. Criticism is more than welcome.
Anyway, withut further delay:

#!/bin/sh

# turn on debugging
set -x

# set up directories
# where is the source
export EDKSRC=`pwd`
# release (target) directory
export RELDIR=`pwd`/reldir
# where can we copy existing header files from?
export INSTALLDIR=/opt/mb-gcc

# make release directory
mkdir -f ${RELDIR}

# first build binutils:
cd ${EDKSRC}/binutils/microblaze
./configure --target=microblaze --prefix=${RELDIR}
make all CFLAGS="-O2 -g -DMICROBLAZE -DEDK" CXXFLAGS="-O2 -g
-DMICROBLAZE -DEDK"
make install

# link microblaze-as to mb-as
ln ${RELDIR}/bin/microblaze-as ${RELDIR}/bin/mb-as 
ln ${RELDIR}/bin/microblaze-ld ${RELDIR}/bin/mb-ld 
ln ${RELDIR}/bin/microblaze-ar ${RELDIR}/bin/mb-ar 
ln ${RELDIR}/bin/microblaze-ranlib ${RELDIR}/bin/mb-ranlib 

# add newly created binutils to the path
export PATH=${PATH}:${RELDIR}/bin

# copy header files from install directory into new release directory
cp -R ${INSTALLDIR}/microblaze/include ${RELDIR}/microblaze/include
cp -R ${INSTALLDIR}/include ${RELDIR}/include

# Now build gcc
cd ${EDKSRC}/gcc
#touch gcc/configure
mkdir build
cd build
../configure --target=microblaze --prefix=${RELDIR}
make all CFLAGS="-O2 -g -DMICROBLAZE -DEDK" CXXFLAGS="-O2 -g
-DMICROBLAZE -DEDK"
make install

ln ${RELDIR}/bin/microblaze-gcc ${RELDIR}/bin/mb-gcc 

# Now build newlib (crt files, libc, etc...)
cd ${EDKSRC}/newlib/microblaze
make

# We've got to pick out the things that we want 
# since there's no `make install`

cp libc.a libm.a ${RELDIR}/microblaze/lib
cp libgloss/microblaze/crt*.o ${RELDIR}/microblaze/lib
