[VOL-5308] - bbsim test failure

Makefile
--------
  o Temporary flag USE_LF_MK=1 added to enable library repo:onf-make use.
  o Default behavior will use legacy makefiles from  repo:bbsim/makefiles/.
  o Fixed typo on line 76

lf/include.mk
makefiles/
-------------
  o Transition bridge for using repo:onf-make.
  o Define variable legacy-mk= as bbsim/makefiles/
  o Replace path variable $(MAKEDIR=) with $(legacy-mk).
  o Replace variable $(ONF_MAKEDIR=) with $(legacy-mk).
  o These edits help break dependency on non-library makefiles/ directory.
    allowing repo:onf-make to be used as a transparent replacement.
