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]
