Follow-up Comment #2, bug #51436 (project octave):

i686 is quite an exotic architecture now-days... Not many 
people have it around now days, but nevertheless other distributions seems to
build it sucessfully e.g.:

https://kojipkgs.fedoraproject.org//packages/octave/4.2.1/3.fc26/data/logs/i686/build.log


I would suspect blas libraries. I assume you are using eithe atlas or
openblas.  Try to rerun make check preloading a reference
blas library (or just recompile against reference blas):


LD_PRELOAD=/usr/lib/libblas.so make check


(adjust the path to your blas library accordingly)

Sincerely,

Dmitri.
