HOWTO build arm-linux toolchain for ARM/XSCALE
----------------------------------------------
above of all;
useradd -G root -g root -d/home/arm arm
mkdir -p /home/arm
chown -R amr /home/arm
chmod -R 77t /home/arm

arm@linux:~$ mkdir dev_home
cd dev_home
mkdir btools kernel
These instructions document how to build an arm-linux tool chain
that contains both little-endian and big-endian target libraries.
1. Packages used:
binutils-2.17.tar.gz
gcc-4.2.1.tar.gz
glibc-2.3.6.tar.gz
glibc-linuxthreads-2.3.6.tar.gz

2. binutils-2.17
tar xvzf binutils-2.17.tar.gz
cd binutils-2.17
mkdir arm-linux
cd arm-linux
../configure --target=arm-linux --with-lib-path=/usr/local/arm-linux/lib:/usr/local/arm-linux/lib/be:/usr/local/arm-linux/lib/soft-float:/usr/local/arm-linux/lib/be/soft-float
make
make install
chmod 777 /usr/local/arm-linux
3. gcc-4.2.1
tar xvjf gcc-4.2.1.tar.bz2
cd gcc-4.2.1
cp $(ATTACHED t-linux file) gcc/config/arm/
vi gcc/config/arm/linux-elf.h
-- remove line that defines LIBGCC_SPEC
vi gcc/config/arm/lib1funcs.asm
-- change line 999 which are:
mov r0, #SIGFPE
bl SYM(raise) __PLT__
to be:
bl SYM (__div0) __PLT__
mov r0, #0 @ About as wrong as it could be.

- change "slibdir = @...@" to "slibdir = @libdir@"
vi Makeconfig
- remove any usage occurrances of -lgcc_eh

- comment out line 5 "weak_alias (setsockopt, __setsockopt)"
vi sysdeps/arm/dl-machine.h
- line 360, remove "static" before function fix_bad_pc24
