Follow-up Comment #2, bug #20501 (project make):

As far as I can see this is not a bug, this is make performing exactly as
described in the manual.  MAKEFLAGS is not a live way of controlling a running
make's behaviour, it is used solely for the purpose of passing down to a
recursive invocation of make; that is why you find they work when you run a
"subsequent call from the makefile", by which I think you mean a recursive
submake invocation.

Please review the make documentation, "5.7.3 Communicating Options to a
Sub-`make'", and verify whether you really have a bug here or not.
