Currently, the ncurses package conditionally defines macros to install
the panel, form and menu libraries. This means we duplicate the install
step for each library type.
Rather than defining a set of macros, this change introduces a variable
for the set of installed libraries, $(NCURSES_LIBS-y). We use this in a
single macro to perform the library installation in one place.
