It's not possible. I suggest you use a callback interface:
have a function in libmonogc.so that can be used to register a callback
and when the GC is initialized (from the metadata/ code) it calls
the function to register a callback.
See for example in metadata/gc.c in the function mono_gc_init()
how GC_finalizer_notifier, GC_oom_fn etc are set (they just
set a static function pointer, using a function to register
the callback would be cleaner).
