New configure test for make fails

[Kai Großjohann]

When I do "make savannah", it invokes ./configure.  And that
invocation fails when testing for the right make version.

I added the following line to the configure script:

echo "xyzzy$(${MAKE} -f test.makefile 123)xyzzy"

With this line, I see the following output from ./configure, called by
"make savannah":

/----
| scp tramp-2.0.36.tar.gz address@hidden:/upload/tramp
| tramp-2.0.36.tar.gz                           100%  256KB  49.9KB/s   00:05   
 
| ./configure

\----

Weird, huh?  Maybe ${MAKE} is set wrongly?  Lessee now...  No,
another statement shows that ${MAKE} is just "make", without the
additional -C argument that I expected.

What to do?
