* dbxread.c, elfread.c, mipsread.c, nlmread.c, os9kread.c:

	Move "no debugging symbols found" test to symfile.c.
	* symfile.c (syms_from_objfile, reread_symbols):  Add
	"no debugging symbols found" test.
	* coffread.c (init_stringtab):  Handle stripped files with a
	stringtab offset of zero gracefully.
	* osfsolib.c (solib_create_inferior_hook):  Use DYNAMIC flag from
	BFD instead of stop_pc heuristic to determine if it is a dynamically
	linked object file.
	* procfs.c (wait_fd):  Handle ENOENT error return from PIOCWSTOP
	ioctl, it indicates that the process has exited.
