I adapted a Script for building a GNU binutils/GCC/Newlib/GDB toolchain. It should be portable. gmp, mpfr and mpc need not be installed.
The script will build binutils, gcc, the newlib C library, gcc again and gdb into ~/arm by default.
Currently there is one issue with the mainline r0ket firmware; in some circumstances the linker for loadables fails to find some library functions gcc inserts on variable initialisations or something. I've found that linking with gcc instead fixes this problem. A fixed version is available from my repo for now.
