* irix5-nat.c, osfsolib.c, solib.c (symbol_add_stub): Handle

	missing or zero-sized .text sections properly.
	* mdebugread.c:  Handle scRConst and scSUndefined storage classes.
	* stabsread.c (scan_file_globals):  Try to resolve symbols
	for shared libraries from the minimal symbol table of the main
	executable first.
