Hi Thomas, the root cause of the build failure on Arm is their library 
fork which lags behind, being at 1.5 release which is at this point 
almost 3 years old.

The only solution in this release cycle is to drop this patch and rebase 
the ones adding support for 3.0.

Considering Arm lack of support and contributions for these PMD over the 
last couple of years, the only long term solution I see to avoid PMD 
code littered with ifdefs and supporting very old releases of the 
library is to drop the Arm version altogether.
