DPDK 20.05 had some deprecation notes after "make config"
and after the build.
For DPDK 20.08, the config note is replaced with a warning
before the config and before the build.
After the warning, there is a pause which can be skipped
with the variable MAKE_PAUSE.

This deprecation process was discussed in the Technical Board:
