svn commit: r291554 - head/share/mk

Log:
  FAST_DEPEND: Allow not using -MP by setting DEPEND_MP blank.
  
  -MP creates empty targets for all dependency files, which can be useful when a
  dependency is deleted from the file system.  This would otherwise cause an
  error for "don't know how to build FOO" since the .depend file is included
  with the dependency registered.
  
  This is mostly a workaround for the misc/dahdi-kmod port using '::' for one of
  its dependencies, while -MP uses just ':'.  This results in an 'Inconsistent
  operator for' error.
