bug#71838: ecl-mito fails to build

[Andreas Enge <andreas@enge.fr>]

Hello,

noticing that lots of ecl-mito clog the bordeaux build farm, I tried a
local build from master. It ends like this:

phase `build' succeeded after 22.6 seconds
starting phase `check'

and then stalls (and presumably would time out after a very long time).
