Installing a Crosscompiler on Your PC : Build Toolchain

One easy way:
  $ wget www.kegel.com/crosstool/crosstool-0.26.tar.gz
  $ tar -xzvf crosstool-0.26.tar.gz
  $ cd crosstool-0.26
  $ sh demo-mipsel.sh

This creates /opt/crosstool/
  mipsel-unknown-linux-gnu/gcc-3.2.3-glibc-2.2.3/bin

Edit demo-mipsel.sh to pick different cpu, gcc, or glibc
