[dpdk-stable] [PATCH 3/3] examples/qos_sched: fix building with GCC 10

[Timothy Redaelli <tredaelli@redhat.com>]

GCC 10 defaults to -fno-common, this means a linker error will now be
reported if the same global variable is defined in more than one
compilation unit.

Fixes: be1e533238c0 ("examples/qos_sched: add TC and queue config flexibility")
