+     MKHOSTOBJ   Can be set to ``yes'' or ``no''.  If set to ``yes'', then for

+                 be suffixed to the name of the object directory created by
+                 ``make obj''.  (This allows multiple host systems to compile
+                 NetBSD for a single target.)  If set to ``no'', then programs
+                 built to be run on the compile host will use the same object
