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.

    10 
    11 On sh[34]-linux, memset function does not work if 2nd argument is negative
    12 and 3rd argument is greater than 12.
    13 for example, memset(ptr, "\xda", 20) sets 0xff instead of 0xda.
    14  
    15 Attached patch fixes this problem.
