Subject: [EXPAND] Added configure --enable-glob and --enable-fnmatch options

Debian's libc6 as of 2.6.1-6 has working glob(3)/fnmatch(3) support.
This patch adds the options --enable-glob and --enable-fnmatch to
the configure script.  By default glob(3) and fnmatch(3) are still
unused.  However, on distros where the glibc is known to work you
may enable these options.
