main_identifier_node is defined to "main" when gigi starts up but redefined to 
something else when the compilation unit really contains a main.  This breaks 
in LTO mode, including for an all-Ada program.

Tested on i586-suse-linux, applied on the mainline.

	* gcc-interfaces/utils.c (create_subprog_decl): Do not redefine
	main_identifier_node.
