.gitlab-ci.d/crossbuilds.yml: Force 'make check' single-threaded for cross-i686-tci
The cross-i686-tci CI job is persistently flaky with various tests
hitting timeouts. One theory for why this is happening is that we're
running too many tests in parallel and so sometimes a test gets
starved of CPU and isn't able to complete within the timeout.
(The environment this CI job runs in seems to cause us to default
to a parallelism of 9 in the main CI.)
