A script for building your own gnu toolchain for ARM. Derived directly from the same script at the mpx project at opencores.org Keep or change the PREFIX in the script to a path where you want the binary to end up. sudo ./build_gcc then put whatever you had in your prefix/bin in the path. The default gnuarm would mean /gnuarm/bin goes in the PATH. clang script I wrote, builds llvm+clang from sources.
