[krbdev.mit.edu #8795] configure: chech for libncursesw, if libncurses is not found

[Дилян Палаузов via RT]

Hello,

I think this statement for LFS was in the past (15 years ago) not valid.

Anyway, it does not matter which kind of system it is.  If libncursesw is available and libncurses is missing,
./configure shall be happy.
