Bug#993043: ensmallen: autopkgtest regression on arm64/i386/ppc64el

[Étienne Mollier]

Control: tags -1 patch pending

Greetings,

the remaining failure affects i386 which, from my experiments,
seems to be caused by the excess double precision.  I consider
pushing an adjustment to the test suite, so it builds with that
option, if there are no objections.

Have a nice day,  :)
