Arvm7 native build fails with this error:
../config/meson.build:364:1: ERROR: Problem encountered:
Number of CPU cores not specified.

This is because RTE_MAX_LCORE is not set. We also need to set
RTE_MAX_NUMA_NODES in armv7 native builds.

Fixes: 8ef09fdc506b ("build: add optional NUMA and CPU counts detection")

In DPDK 19.11 the ARMv7 config says armv7 does not support NUMA.
Pleas set NUMA_NODES to 1
