165# kmdb dmods must *not* stray from the module API.  To ensure that they don't,

167# that they can legally use.  The link test object is, however, only built when
168# kmdb itself is built.  Requiring module developers to build kmdb first would
169# be painful, so by default, module-level builds don't do the link test (the
170# $(POUND_SIGN) assignment below takes care of that).  Builds of the entire
171# tree can, however, guarantee the construction of kmdb first, and as such can
