svn commit: r228860 - head/sys/conf

New Revision: 228860
URL: http://svn.freebsd.org/changeset/base/228860

Log:
  Make another clang warning, -Wempty-body, non-fatal during kernel
  builds.  All the instances of this warning in our tree are completely
  harmless.  (Most of the empty bodies look to be used simply as reminder
  for the developer to add something later.)
  
  While here, assign to CWARNEXTRA with ?=, so it can be overridden
  easily, if needed.
