gitlab-ci: cross-i386-system job timeouting

[Philippe Mathieu-Daudé]

Hi,

With all the recent pull requests merged, I'm now seeing
the cross-i386-system reaching the timeout limit:

ERROR: Job failed: execution took longer than 1h20m0s seconds

Maybe it was borderline and the addition of a new machine with
new types was too much.

What to do now? Split the job yet again?

Thanks,

Phil.
