* infrun.c (wait_for_inferior): Add support for dynamic function

	trampolines.  These are pieces of code between the caller and the
	callee that figure out the address of the callee's code at run
	time.  Upon entry, we can't figure out the callee's address, so we
	set a breakpoint within the trampoline where the address will be
	known, and continue the target.  Once we hit the breakpoint, we
	break at the callee's address and proceed as usual.
start-sanitize-gm
	* config/tm-magic.h:  Define DYNAMIC_TRAMPOLINE_NEXTPC.  Turn off
	IN_SOLIB_CALL_TRAMPOLINE and IN_SOLIB_RETURN_TRAMPOLINE.
