config: fix generated config files when GREP_OPTIONS set --color=always

grep is used when generating some .in files (in config.gen). If GREP_OPTIONS
contains --color=always, then the generated files will contains some escape
sequences setting the color, and mconf would choke on those escape sequences.

Always set and export an empty GREP_OPTIONS to avoid that.

     8 # It is expected that this script is only to be run from the
     9 # source directory of crosstool-NG, so it is trivial to find
    10 # paths.mk (we can't use  ". paths.mk", 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.
