    grep: support Perl regular expression
    
    Supporting Perl regular expression is disabled with '--disable-perl-regexp'
    but the manpage of 'grep' shows the '-P' option and returns below error:
    "/bin/grep.grep -o -P 'PATTERN' file
     /bin/grep.grep: support for the -P option is not compiled into this \
                   --disable-perl-regexp binary"
