For some combination of race and class, racial substitution level is doing that. For example, a 1st level Dwarf fighter who takes racial substitution level has a HD of d12.
And, in most cases, the toughness you have suggested is represented by either high Con or Toughness feat. Or, in case of monster races, with the number of racial HD.
In case of Half-Orc, Orcs and Half-Orcs are not particularly tough race (high Con or some racial HD) in current DnD. They are stronger, but not tougher than human race. If your image of Orcs and Half-Orcs are much tougher, maybe you should better change the stats of those races in your campaign.
