configure: fix ncurses 'configure' issue on Solaris 10 (Bug#10677)

Browse Source 
* configure.in (LIBS_TERMCAP): Default this to the result of
the tputs library search.  Do a run-time test for the linkability
of tputs unless cross-compiling, as that's more reliable if the
link flags and libraries are messed up.  Don't change LIBS as
a result of the test, as that may mess up later tests.
