svn commit: r319859 - head

New Revision: 319859
URL: https://svnweb.freebsd.org/changeset/base/319859

Log:
  Add support for "make universe_kernels -DMAKE_GENERIC_KERNELS" to build
  just the GENERIC kernels for each arch (including variations such as
  GENERIC-NODEBUG, GENERIC64, etc).
  
  This helps with quickly doing a test build for all[*] arches without
  building dozens of variant kernels for the arches that have lots of
  hardware/board/system variations.
  
  [*] Not all arches have a generic kernel (but they probably should for
  test-building purposes, even if it can't boot on any real hardware).
