David Freese cddab9240b Fix LDFLAGS
* Link with all needed libraries. Required when linking with
      --no-add-needed or the experimental gold linker, which has this
      behaviour by default.
    * On X11 platforms we should explicitly link  with libX11 because we
      use XCreatePixmap via the FLTK fl_create_offscreen macro
