These errors mean that:

(a) you're using the system implementation of GNU glob/fnmatch (which is to
be expected since you're on a system that provides GNU libc; the built-in
versions are only used on systems that don't have GNU libc)

AND (b) your version of GNU libc still has bugs in its implementation of
glob/fnmatch that have been fixed in newer versions.

There's no change in behavior from previous versions of GNU make, except
that in this version we have a regression test that will show the problem.

Here's the GNU libc bug that you're experiencing:

Back when GNU make first got a regression test suite, diff -u wasn't so
common.  I guess these days it's much more common so we could consider it.
