Something like this:

$capabilities = array( ... );
foreach ( array( 'administrator', 'editor' ) as $role ) {
   $role =& get_role( $role );
   if ( ! $role )
       continue;
   foreach ( $capabilities as $cap )
      $role->add_cap( $cap );
}

Caution, that probably triggers a boat-load of queries. add_cap() should
probably accept an array of capabilities to make that less taxing. (It only
runs on activation, though.)

Keep in mind you still need to handle meta capabilities yourself.
