Drats. It looks like the coreutils source repo will need something like:

diff --git a/bootstrap.conf b/bootstrap.conf
index 7def1f9..30ce621 100644
--- a/bootstrap.conf

I've not analysed whether that will work (in all cases).

I've applied that locally and generated an untested tarball with `make dist`:
https://www.pixelbeat.org/cu/coreutils-8.27.4-3c9d7.tar.xz

Could you test that one out?

I'm guessing that "failure" might be locale related.
Could you attach the tests/test-suite.log file generated with:
  make TESTS=tests/misc/sort-debug-keys.sh SUBDIRS=. VERBOSE=yes check
