  <!-- Wrapper for slides -->
  <div class="carousel-inner">

  <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></span>
  </a>
</div>

You could conditionally show the controls by determining the current slide like this..

$('#myCarousel').on('slid.bs.carousel', function (ev) {
  var carouselData = $(this).data('bs.carousel');
  var currentIndex = carouselData.getActiveIndex();

  if (currentIndex >= 1) {
    $('.left').show();
  }
  else {
    $('.left').hide();
  }

  if (currentIndex === (carouselData.$items.length-1)) {
    $('.right').hide();
    $('.left').show();
  }
  else {
    $('.right').show();
  }
})
