  Okay, as pointed out, there is a bug internal to the libc loader and that
should be reported appropriately. 
  I note however that your list seems to miss the libxml2 library dependancy
try to add -lxml2 to the linking phase.

  Providing binding for Java makes sense, I don't know how hard it is nowadays,
I didn't do C <-> Java bindings for nearly a decade :-) , maybe it's time
I look at this again.
