	* init.c (__gnat_initialize): Call an Ada subprogram to perform the
	table registration calls when need be. Ensures no reference to the crt
	ctors symbol are issued in the SJLJ case, which avoids possible
	undefined symbol errors in the case of modules to be statically linked
	with the kernel.

against a constant System flag value. */
