In http://landley.net/aboriginal/bin grab the cross-compiler-*.tar.bz2
tarballs, extract them, add the "bin" subdirectory of each to the
$PATH. Congratulations, you have cross compilers set up. (They're
statically linked and relocatable, so should run just about anywhere.
If they don't, let me know and I'll fix it.)
Example build:
make ARCH=sparc sparc32_defconfig
PATH=/home/landley/simple-cross-compiler-sparc/bin:$PATH \
make ARCH=sparc CROSS_COMPILE=sparc-
