| Octave doesn't ever reference these symbols, so I suspect it's a

The file src/DLD-FUNCTIONS/glpk has this code, which is probably
related to the problem:

  #if defined (HAVE_GLPK)

  extern "C"
  {
  #if defined (HAVE_GLPK_GLPK_H)
  #include <glpk/glpk.h>
  #else
  #include <glpk.h>
  #endif

  #ifdef GLPK_PRE_4_14

  #ifndef _GLPLIB_H
  #include <glplib.h>
  #endif
  #ifndef lib_set_fault_hook
  #define lib_set_fault_hook lib_fault_hook
  #endif
  #ifndef lib_set_print_hook
  #define lib_set_print_hook lib_print_hook
  #endif

  #else

  void _glp_lib_print_hook (int (*func)(void *info, char *buf), void *info);
  void _glp_lib_fault_hook (int (*func)(void *info, char *buf), void *info);

  #endif
  }

Is GLPK_PRE_4_14 defined in your config.h file when you use glpk 4.32?

Has the glpk interface changed again to remove the _glp_lib_print_hook
and _glp_lib_fault_hook functions?
