Like I already said, all the source files are in the same tree as the C compiler. So you already have them. It looks like crosstool-ng does support building any of the language front-ends supported by GCC, see: https://github.com/crosstool-ng/crosstool-ng/blob/c969be1880f99b6da4d98afd7bda641b7868a717/scripts/build/cc/gcc.sh#L37 Maybe you should just spend some time investigating crosstool-ng.
