New Revision: 356111
URL: https://svnweb.freebsd.org/changeset/base/356111

Log:
  Use LLVM as default toolchain for all PowerPC targets
  
  This enables LLVM as the default compiler for powerpc, powerpc64, and
  powerpcspe, as well as LLD as the default linker for powerpc64.
  
  LLD is not yet ready for prime time for powerpc and powerpcspe, but work is
  continuing on it.
