While the presence of gl_LIBTOOL is a boolean:

      --libtool             Use libtool rules.
      --no-libtool          Don't use libtool rules.

# - libtool         true if --libtool was given, false if --no-libtool was
#                   given, blank otherwise

the gl_LGPL attribute has more than two possible values:

      --lgpl[=2|=3]         Abort if modules aren't available under the LGPL.
                            Also modify license template from GPL to LGPL.
                            The version number of the LGPL can be specified;
                            the default is currently LGPLv3.

# - lgpl            yes or a number if --lgpl was given, blank otherwise
