Most likely he thinks/thought that since there are two different make processes with a python process in between the command line override wouldn't leak to the child make. But (from the manual):

> Likewise variables defined on the command line are passed to the sub-make through MAKEFLAGS. (5.7.3)

> The special variable MAKEFLAGS is always exported (unless you unexport it). (5.7.2)

The manual doesn't actually say that MAKEOVERRIDES is exported like MAKEFLAGS but I assume it is.

Follow-up Comment #5:

As Martin says, if the variable is set ON THE COMMAND LINE, it will absolutely
take precedence over the setting in a makefile variable (unless overridden
with override).

But, you said you has set this IN THE ENVIRONMENT which is very different;
values set in the environment should not take precedence over values set in
the makefile (as long as -e is not set).

So, you'll have to investigate why/how this variable assignment is appearing
in your command line (in MAKEFLAGS).

I'm going to close this; you can continue to post here but better would be to
discuss on the mailing list, until/unless we discover a bug.
