New Revision: 221503
URL: http://svn.freebsd.org/changeset/base/221503

Log:
  Make cross-compiling using clang work better, by respecting the
  LLVM_HOSTTRIPLE that is defined during the cross-tools stage.
  
  Using clang, you can now build amd64 world and kernel on i386, and vice
  versa.  Other arches still need work.
