You need to read all the applicable bits in the standard before
calling behavior incorrect. In particular, the Macros section has
this line earlier in it:
The result of setting MAKEFLAGS in the Makefile is unspecified.
So if you want POSIX-like behavior, don't do that; if you do that,
you're at the whims of GNU make's choices.
