  Summary: comms/svxlink: Fix build with libc++ 3.8.0
  
  During the exp-run in bug 208158, it was found that comms/svxlink gives errors
  with libc++ 3.8.0 [1]:
  
  /wrkdirs/usr/ports/comms/svxlink/work/svxlink-15.11/src/async/audio/AsyncAudioDe
  +viceAlsa.cpp:551:7:
  error: call to 'abs' is ambiguous
    if (::abs(real_rate - sample_rate) > 100)
        ^~~~~
  
  This is because abs() is being called with an unsigned argument.  Fix this by
  casting 'real_rate' to int, since it was assigned from 'sample_rate' anyhow.
