Clean up patches for delta88 nested function support.

	* m88k/m88k.c (struct option): Rename to struct options.
	* m88k/dolph.h (INITIALIZE_TRAMPOLINE): Delete here.
	* m88k/sysv3.h (INITIALIZE_TRAMPOLINE): Delete ifdef and comments.
	* libgcc2.c (__enable_execute_stack): Check for __sysV88__ not
	__DOLPHIN__ or sysV88.
