gnulib-tool.py: Fix some unbound variables.

[Collin Funk]

In GLEmiter.autoconfSnippets I see many warnings that a 'solution'
variable may be unbound when it is used.

         if solution:  # Solution may be unbound here.
             emit += self.autoconfSnippet(module, toplevel,
                                          disable_libtool, disable_gettext, 
replace_auxdir, '  ')

It seems that the unbound variable will evaluate to 'False', which
would explain why it still works. Still not good practice. :)

This patch silences the warning by initializing solution to False at
the start of each loop. Easy fix.
