Log:
  MFC r264345:
  
  Amend r263891, by making clang default to DWARF2 debug info format for
  all FreeBSD versions, not just 10.x and earlier.  Apparently too many
  people seem to have trouble with post-1993 formats.
  
  Also remove the related notes about messing with kernel configuration
  files from UPDATING, which are now superfluous.

-	Clang and llvm have been upgraded to 3.4 release.  Please note that
-	clang 3.4 now defaults to DWARF4 debug information format when you
-	specify -g.  Since kgdb(1) only supports DWARF2, you should update any
-	customized kernel configurations which include debug information to
-	explicitly use -gdwarf-2, e.g:
-
-	  makeoptions	DEBUG=-gdwarf-2
-
-	This has already been applied to the appropriate GENERIC configuration
-	files, so if you inherit from those, no changes are required.
