[dpdk-stable] Why was "drivers/crypto: fix build with -fno-common" not picked for 19.11 stable back then?

[Christian Ehrhardt]

Hi,
there is an old patch [1] which back then was not considered/taken
into 19.11 series.
This is now breaking Clang build [2].

Since you were the Author/Maintainers back then I wanted to ask if
there was a reason to not pick it? If it should be picked now and if
there are any special things to consider for a backport?

Chiming in/subscribing to the bug would also be appreciated.
