lang/maude: fix build on GCC architectures

[linimon]

Summary

Don't link unconditinally with $NCURSESLIB. When NCURSESLIB is /usr/lib and the system compiler is base GCC, GCC from ports (currently GCC9) is used. Passing -L/usr/lib makes GCC try to link to base libstdc++ instead the one from ports.

Also add USES=localbase:ldflags.

shouldn't Mk/Uses/ncurses.mk be adapted to do this properly itself?

Since -I and -L are passed here manually (instead of in ncurses.mk), I didn't want to touch ncurses.mk. If someone ncurses.mk adds appriopriate -I and -L sometime, then this .if should also be put there.
