[Buildroot] [PATCH] util-linux: add -lcurses to LDFLAGS when static linking

[Chris Packham]

When linking statically with -lreadline we also need to specify
-lcurses.

I think this should address the following build failures although I've only
confirmed the two quoted above.

I'm not sure that this is the "right" fix but it seems to do the trick. I also
tried using LIBS instead of LDFLAGS which got the configure step to pass but
didn't propagate to the final link.
