Public bug reported:

the version of make has what appears to be a broken for the
MAKEFILE_LIST macro.

This is commonly used to get the currently loaded makefile.

However for some reason in this distribution the variable is not
behaving as it should be.

>From https://www.gnu.org/software/make/manual/html_node/Special-
Variables.html

MAKEFILE_LIST

    Contains the name of each makefile that is parsed by make, in the
order in which it was parsed. The name is appended just before make
begins to parse the makefile. Thus, if the first thing a makefile does
is examine the last word in this variable, it will be the name of the
current makefile. Once the current makefile has used include, however,
the last word will be the just-included makefile.

However in the attached program you can see a use that this is violated.
The "ZZZfiles" definition has been set in wibble.mk which occurs before
the include statement that includes another.mk  however another.mk is in
the variable as shown when the variable is printed.
