[MPlayer-dev-eng] [PATCH] build: Check if SCTP is available

[Alexander Strasser]

  Test for SCTP and remove it from the list of libavformat
protocols in case the test did not succeed or the feature
was explicitly disabled.

  Unconditionally trying to build it, as it was done before
if you had a new enough libavformat version that contains
that feature, is obviously not a good idea.

  This patch is closely based on a patch from Johan Andersson.
