[pkg-go] Bug#855487: tendermint: FTBFS (32-bit): TestByzantine index out of range

[Aaron M. Ucko]

Source: tendermint
Version: 0.8.0+git20170113.0.764091d-2
Severity: important
Justification: fails to build from source

Thanks for taking care of #854813, which allowed the automatic builds
on arm64 and ppc64 to succeed.  Alas, 32-bit builds (on armel, armhf,
and i386) are still failing -- on i386, for instance, I see

Could you please take a look?

(The consensus test also failed on ppc64el for an apparently unrelated
reason, which I'll report separately.)

Thanks!
