bug#37425: Go 1.12.7 fails to build on i686-linux

Hello,

Go 1.12.7 has test failures on i686-linux, on ‘core-updates’:

(From
<https://ci.guix.gnu.org/log/pv1clywg43pb8fknrd2zs1zk4wd26fq0-go-1.12.7>.)

I found these issues that suggest the test has been flaky:

  https://github.com/golang/go/issues/4155
  https://github.com/golang/go/issues/28574

Unless someone has a better idea, I’d suggest skipping this test on
i686.

Thoughts?

Commit b938892551816aedd01fd32b7eb1d5e061afce32 patches the test to skip
it on all platforms after I had experienced it on x86_64 as well (the
test was in fact already skipped on some platforms.)

According to <https://github.com/golang/go/issues/27636>, the underlying
issue has been fixed just 11 days ago.
