That allows the files to be compiled, but some tests fail:

Files examined: 305
Ran 4241 tests, 4197 results as expected, 5 unexpected, 39 skipped
5 files contained unexpected results:
  src/emacs-module-tests.log
  src/callint-tests.log
  lisp/subr-tests.log
  lisp/net/tramp-archive-tests.log
  lisp/emacs-lisp/gv-tests.log

LC_ALL=C has been there from the very beginning, which means that in all
these years, nobody has tried "make check" with non-ASCII chars in their
paths.  :-)
