Hi folks,

This is small update to libsndfile as part of my effort to package
MediaGoblin. Essentially, the ogg/flac/vorbis/opus support is only on if
*all four* libraries are present, and opus is currently missing.

Before applying this patch, the configure phase for libsndfile reports:

  checking for flac >= 1.3.1 ... yes
  checking for ogg >= 1.3.0 ... yes
  checking for vorbis >= 1.2.3 ... yes
  checking for vorbisenc >= 1.2.3 ... yes
  checking for opus >= 1.1 ... no           <<< LOOK HERE

  configure: WARNING: *** One or more of the external libraries (ie libflac, libogg and
  configure: WARNING: *** libvorbis) is either missing (possibly only the development
  configure: WARNING: *** headers) or is of an unsupported version.
  configure: WARNING: ***
  configure: WARNING: *** Unfortunately, for ease of maintenance, the external libs
  configure: WARNING: *** are an all or nothing affair.

  -=-=-=-=-=-=-=-=-=-= Configuration Complete =-=-=-=-=-=-=-=-=-=-=-

    Configuration summary :

      External FLAC/Ogg/Vorbis/Opus : ....... no


After this patch the libsndfile configure shows:

  checking for flac >= 1.3.1 ... yes
  checking for ogg >= 1.3.0 ... yes
  checking for vorbis >= 1.2.3 ... yes
  checking for vorbisenc >= 1.2.3 ... yes
  checking for opus >= 1.1 ... yes         <<< LOOK HERE

  -=-=-=-=-=-=-=-=-=-= Configuration Complete =-=-=-=-=-=-=-=-=-=-=-

    Configuration summary :

      External FLAC/Ogg/Vorbis/Opus : ....... yes
