[pkg-go] Please give back golang-1.8 (1.8.3-1) on s390x

[Anthony Fok]

Hello,

There seems to be a hiccup when golang-1.8 (1.8.3-1) was last built
for s390x on zemlinsky.

Seeing the logs at

    https://buildd.debian.org/status/logs.php?pkg=golang-1.8&arch=s390x

It seems that zemlinsky fails consistently "Illegal Instruction" early
in the build,
while both zandonai and zani consistently succeed.

    gb golang-1.8_1.8.3-1 . s390x

Perhaps it is too much to ask, but would it be possible to set some
kind of automatic give-back whenever golang-1.8 (or future golang-1.9)
fails on zemlinsky?

Or, better yet, is there a way to find out what went wrong on
zemlinsky?  Is it an older machine with an older CPU that does not
support some newer CPU instructions?  (Sorry, I know nothing about
s390x and I am likely completely wrong.)

Many thanks!

Anthony
