New Revision: 359424
URL: http://svnweb.freebsd.org/changeset/ports/359424
QAT: https://qat.redports.org/buildarchive/r359424/

Log:
  On some Tier-2 platforms (e.g. PowerPC), clang kind of works and so is
  installed but is not cc. On such platforms, clang is usually not default
  for a reason and so using it for C++11 is unwise. Instead, fall back to
  newer GCC. On i386 and amd64, clang works even if it isn't the default,
  so continue using it there.
  
  This fixes the build for Boost, among other software, on PowerPC.
