Re: Fix tight loop on recursively-defined symbols

sy_resolving ought to not be set for a struct local_symbol, but it is
apparent from local_symbol_make that the field is not initialised.

	* symbols.c (resolve_symbol_value): Invoke LOCAL_SYMBOL_CHECK
	before looking at add_symbol->sy_flags.sy_resolving.
