cc/gcc: pass the language list to the core backend

As the core backend can be used to also build the bare-metal compiler,
we have to tel it what languages to build.

    10 # paths.sh (we can't use  ". paths.sh", as POSIX states that
    11 # $PATH should be searched for, and $PATH most probably doe
    12 # not include "."), hence the "./".

    17 Usage: ${myname} <src_dir> <dst_dir> <base> <inc> [sed_re]
    18     Renumbers all patches found in 'src_dir', starting at 'base', with an
    19     increment of 'inc', and puts the renumbered patches in 'dst_dir'.
    20     Leading digits are replaced with the new indexes, and a subsequent '_'
    21     is replaced with a '-'.
    22     If 'sed_re' is given, it is interpreted as a valid sed expression, and
    23     is be applied to the patch name.
    24     If the environment variable FAKE is set to 'y', then nothing gets done,
    25     the command to run is only be printed, and not executed (so you can
    26     check beforehand).
    27     'dst_dir' must not yet exist.
