• Add alsa-devel BuildRequires: we care for ALSA support to be built and
  thus need to ensure we get the dependencies in place. In the past,
  alsa-devel was pulled in by accident: we buildrequire libgnome-devel.
  This required esound-devel and that in turn pulled in alsa-devel for us.
  libgnome is being fixed to no longer require esound-devel.
