Log:
  Fix bootstrapping libmd on older systems after r314709.
  
  This follows another fix to bootstrap libmd after r313404.  The
  MD5FileChunk prototype is needed to build libmd, but it is
  only reliably in the src tree's sys/md5.h header.  Rather than
  polluting the legacy build with this header for the entire build,
  just symlink it in here for now as is done in the elftoolchain
  build.  Libmd is already referencing other src tree headers by
  its used of CFLAGS+= ${SRCTOP}/sys/crypto/sha2.  This, and
  other uses of CFLAGS+= ${SRCTOP}/sys..., may later change to
  be in the legacy mechanism.
