[scripts] ext-toolchain.sh: add option to write .config

Add a new --config option to generate a .config from a given toolchain,
this allows for easy integration of external toolchains, e.g.

  ./scripts/ext-toolchain.sh --toolchain /opt/mips-2011.03 --cflags "-muclibc" --config atheros

to setup a ready-to-compile atheros target using the external CodeSourcery toolchain.
