This sets the --with-shared switch for the configure script so that
ncurses is compiled as a shared library in addition the default which is
a static library.
Without the --with-shared switch ncurses will only be compiled as a
static library.
To properly set the environment variables LOCAL_LDFLAGS and
LOCAL_LDFLAGS2, a case in the configure script had to be updated to
include '*serenity*'.
Much redundancy is removed from package scripts with this system.
It also supports simple dependency management, uninstalling (through
BSD ports style plist files), cleaning up after itself (with clean,
clean_dist, clean_all commands), etc.
