It is sad that Gnulib maintainers aren't prepared to cater to a GNU
project, and an important one such as Make.  These are special
requirements that only a handful of GNU project could ever have, and
for good reasons, so supporting their needs should be a no-brainer.

#2 would require that we promise to have Make 4.3 available from here
to eternity.  Is that feasible?

Can you list the Gnulib functions we currently use?  I mean only those
which Make calls directly, not their Gnulib dependencies.  Perhaps we
could then prepare a fake-gnulib module with trivial implementations
of those functions, which could be used by build.sh instead of the
real Gnulib functions.  (Some Gnulib functions are replacements for
those found in every C library, and those could be simply ignored in
the build.sh build, relying on libc to do a reasonably good job.)  Of
course, this would mean the need to add such stubs every time another
Gnulib function is added to Make, so it is still a maintenance burden
of sorts.  But maybe it isn't too heavy?
