    crossgcc: Add option to build gcc for specific languages
    
    Add an option `--languages` which takes a list of target languages to
    buildgcc. That list gets passed through to the configure step for
    building gcc.
    
    Also alter the Makefile to pass $(BUILD_LANGUAGES) to that option, if
    this variable is set.
