  Now you can type "make" to build BIND 10. Note that if you intend to
  run "make check", you must run "make" first as some files need to be
  generated by "make" before "make check" can be run.

  When running "make install" do not use any form of parallel or job
  server options (such as GNU make's -j option). Doing so may cause
  errors.
