New Revision: 442531
URL: https://svnweb.freebsd.org/changeset/ports/442531

Log:
  Replace the general USE_GCC=yes when building for powerpc64 by the
  specific USE_GCC=5 to be future proof when GCC 6 becomes the default
  (since USE_GCC=yes would then pull in lang/gcc6 which we obviously
  cannot require to build gcc6 itself nor gcc6-devel).  This also helps
  users who play with GCC_DEFAULT in Mk/bsd.default-versions.mk.
