Bug 225834: [PATCH] lang/ghc: fails to build with ncurses from ports

ports ncurses build fix

After switch to clang for build, ghc fails to build with ncurses from ports:

configure: error: in
`/usr/local/ports/lang/ghc/work/ghc-8.0.2/libraries/terminfo':
configure: error: curses headers could not be found, so this package cannot be
built
See `config.log' for more details

NCURSESINC points to NCURSESBASE/include/ncurses while ncurses.h includes files
with path relative to include directory:

In file included from conftest.c:52:
/usr/local/include/ncurses/ncurses.h:60:10: fatal error:
'ncurses/ncurses_dll.h' file not found
#include <ncurses/ncurses_dll.h>
	 ^~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

Proposed patch fixes build by altering NCURSESINC. Was tested with ncurses from
base and ports on all supported releases.
