[John Baldwin]

Author: jhb

New Revision: 359275
URL: https://svnweb.freebsd.org/changeset/base/359275

Log:
  Disable rarely used architecture variants in make universe by default.
  
  If EXTRA_TARGETS is defined, build all supported architecture
  variants.  By default, build architecture variants needed to provide
  code coverage or that are commonly used.
  
  Use this to disable building of all the hard-float and little-endian
  MIPS architecture variants along with n32 by default.
