Building -current with clang on amd64

[Jan Danielsson <jan.m.danielsson%gmail.com@localhost>]

Hello,

   I haven't built -current in a while, so I'm not sure if anything has
changed.

   This is what I did:
   1) Installed NetBSD/amd64 6.1.4
   2) Checked out netbsd -current from cvs
   3) Noticed that llvm/clang was in-tree, so no "make checkout"
   4) Set:
export MKUNPRIVED=yes
export MKLLVM=yes
export MKLIBCXX=yes
export HAVE_LLVM=yes
      (and also set build directories so that it doesn't mess up the
source tree)
   5) Run "./build.sh tools"

   This eventually fails with:

------------------------------------------

   Are there additional steps needed?  It's not surprising that it
doesn't recognize -std=c++11, because it hasn't even gotten around to
building clang yet.

   Seems like it's assuming HAVE_LLVM before MKLLVM somewhere?
