[ upstream commit a462a6a9e7705e0a8e855ed42377041ff0efc908 ]
There are random build errors in test reports [1]. Build error
is not directly related to DPDK but observed during DPDK build.
When I get similar unexpected build errors in my system, found
out that /dev/null is invalid.
It seems ICC overwrites the /dev/null with "icc -o /dev/null" instead
of sending output to /dev/null. This is not always reproducible, so
hard to say what exactly is triggering the error.
I suspect test-report build errors can be because of the same reason,
and it is good to add a protection for this case.
Instead of sending output to /dev/null save it to the tmp folder and
remove it back when done.
