Who's the upstream owner of GNUmakefile?

[Zack Weinberg]

I just pushed a commit that partially reverts a `make fetch'.

    Partially revert e54e3f90: restore use of $(MAKE) in error message.

    In commit 14d58bfd, the error message printed by the
    ‘abort-due-to-no-makefile’ rule in GNUmakefile was changed to refer to
    the value of ‘$(MAKE)’ instead of a literal ‘make’.  A subsequent
    ‘make fetch’ (e54e3f90) clobbered this.  Put it back.

Clearly we need to send the change to this error message upstream, but
I don't know who the upstream for this file is.
