This appears to break Octave (see
<https://hydra.gnu.org/log/gx7z8zd3x113605gpnjp6adx98qwy9fy-octave-4.0.0>):

--8<---------------cut here---------------end--------------->8---

The undefined symbol (demangled: ‘Fl_XFont_On_Demand::value’) is defined
in Fltk’s ‘fl_font_xft.cxx’.  However, looking at the build log of Fltk,
this file is apparently not compiled, which sounds like a bug in Fltk’s
build system.

Could you look into it?

Thanks in advance.  :-)
