Some tests fails often than other tests (when run in multiple jobs), so
rarely (on a big machine, with 32 cores and by using -j32) a test
fails twice and so make check RECHECK=yes fails.
This patch only avoid this rare failure that can be annoying if you are
releasing a new package (on Fedora or RHEL for example) since you need
to re-build all the architectures only for a false positive on a
single architecture.
