Bug#1028862: xorg-gtest: FTBFS: dh_auto_test: error: make -j1 check "TESTSUITEFLAGS=-j1 --verbose" VERBOSE=1 returned exit code 2

Hello.

I can also reproduce this build failure.

My build environment is made of virtual machines in the cloud
with either 1 CPU or 2 CPUs.

This bug happens randomly, but the failure rate seems to depend on the machine.

On systems with 2 CPUs, the failure rate I get is around 50%.
On systems with 1 CPU, the failure rate I get is 100%.

Therefore I suggest using GRUB_CMDLINE_LINUX="nr_cpus=1" in /etc/default/grub
to reproduce it.

Thanks.
