Why don't you exit the subroutine using return and let the calling procedure do the last, next or whatever, depending on what you return? Something like this: 
sub loop_control { 
    if ($x > $stop) { 
         return "last";
     } elsif ($y ne $text) {
        foobar();
     } else {
         return "next"; 
     }
}

# ...
my $return_status = loop_control();
last if $return_status eq "last";
next if $return_status eq "next";
# ...

The alternative is to pass the array (or an array_ref) to the subroutine and loop through the array elements within the subroutine.

In both cases, you avoid the warning (and avoid suppressing this warning) and you gain a better control on what to do, say, before jumping to the next element or exiting the loop altogether. For example, you could use a continue block or a redo, or you could change the two relevant lines above to print some debug statements: 

say "exiting the loop" and last if $return_status eq "last";
say "going to next element" and next if $return_status eq "next";
