 I believe the paragraph you quote is referring to a user setting 
 MAKEFLAGS in the environment before running make.  In otherwords, if a 
 user sets MAKEFLAGS="-D FOO BAR=baz", make should accept it.
 
 The paragraph of interest on what make sets MAKEFLAGS to before 
 makefiles are processed is:
 
 ``Before the makefile(s) are read, all of the make utility command line 
 options (except -f and -p) and make utility command line macro 
 definitions (except any for the MAKEFLAGS macro), not already included 
 in the MAKEFLAGS macro, shall be added to the MAKEFLAGS macro, quoted in 
 an implementation-defined manner such that when MAKEFLAGS is read by 
 another instance of the make command, the original macro's value is 
 recovered.''[1]
