HOWTO build arm-linux toolchain for ARM/XSCALE
----------------------------------------------

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-2.16.tar.gz
    gcc-3.4.4.tar.gz

   make install
   chmod 777 /usr/local/arm-linux


3. gcc-3.4.4

   tar xvzf gcc-3.4.4.tar.gz
   cd gcc-3.4.4

   cp $(ATTACHED t-linux file) gcc/config/arm/
   vi gcc/config/arm/linux-elf.h

      - change "BUS_ISA" to be "CTL_BUS_ISA" lines 103 and 104
   vi config.make.in
      - change "slibdir = @...@" to "slibdir = @libdir@"
   vi Makeconfig
      - change all occurrances of "O2" to "O"
