The Makefile is rejecting all files with for a given prefix (here
"board-plasmacloud_pa1200") when it didn't match a known suffix. Instead it
stops the build with an error like:
Makefile:135: *** Unrecognized board-file suffix '.ipq4019' for 'board-plasmacloud_pa1200.ipq4019'. Stop.
The correct suffix for the QCA4019/hw1.0 is qca4019 and not ipq4019.
