I think it is intentional that if user writes -latomic explicitly, then it
isn't ignored unless using -Wl,-z,ignore explicitly on the command line.

It means that all the libraries later on the command line are not as-needed,
even when user used -Wl,-z,ignore on the command line.
With libatomic_asneeded.so or --push-state --as-needed -latomic --pop-state
that particular occurrence of -latomic is --as-needed regardless of
everything else, the rest follows what user asked for.
