bug#27878: eieio :static test failure on Debian armhf buildd

[Rob Browning]

Now that the tests are running on all of the buildd's there was less
trouble than I'd imagined, but there were a couple of failures:

  https://buildd.debian.org/status/package.php?p=emacs25&suite=sid

In particular the armhf tests failed like this
(https://buildd.debian.org/status/fetch.php?pkg=emacs25&arch=armhf&ver=25.2%2B1-3&stamp=1501385944&raw=0):

I'd be happy to help test on one of our porterboxes if that ends up
being useful.
