    # (https://developer.apple.com/library/mac/qa/qa1118/_index.html) says that
    # static linking works just fine, just do not use it for libc (or other
    # libraries that make system calls). ncurses use -static only for linking
    # the curses library, then switches back to -dynamic - so they should be fine.
    # FIXME: for target, we only need tic (terminfo compiler). However, building
    # it also builds ncurses anyway, and dedicated targets (install.includes and
    # install.progs) do not do well with parallel make (-jX).
