Tracing into __errno_location reveals that actual implementation is in
__GI___errno_location, into which the _dl_runtime_resolve RETs. For
__GI___errno_location I do have line numbers and file name showed. Still, for
__errno_location the result is as it was, unlike for __GI___errno_location:
(gdb) ptype __errno_location
type = int ()
(gdb) ptype __GI___errno_location
type = int *(void)
