Comment (by vulcan_@…):

 I had a look at ass_shaper.c and I see that there is a condition
 `CONFIG_HARFBUZZ` that is controlling the use of the missing symbols, so
 it is not defined somehow. There is an include:
 {{{
 #ifdef CONFIG_HARFBUZZ
 #include <hb-ft.h>
 enum {
     VERT = 0,
     VKNA,
     KERN
 };
 #define NUM_FEATURES 3
 #endif
 }}}
 that suggest that the hb-ft.h would resolve the missing symbols if it was
 included … it should be included but is maybe not found .. i certainly
 could not. But `CONFIG_HARFBUZZ` must be defined because all references to
 the `hb_` symbols are inside IFDEFs

 hmmm ...
