toplevel configure.in simple cleanup

[Nathanael Nerode]

Part of my collection of easy cleanups to make top level configure.in a
smaller target for autoconfiscation...

This patch eliminates a redundant test from configure.in; libgui is included 
in host_libs unconditionally, so doesn't need to be included conditionally 
one line down!  As far as I know there's no conceivable reason to include 
it twice.
