Unfortunately this is a bug with devtool (and or kernel-yocto.bbclass)
and not with the meta-xilinx metadata.
The issue is that meta-xilinx provides kmeta files locally from the
meta-xilinx layer. Devtool makes some assumptions about files provided
by the layer not being needed during source extraction process,
however for the kernel it also assumes it can just run the configure
task whilst not allowing the workdir to have these files. I am not
very familiar with devtool so I am not sure how to fix this properly,
however a change like below (which is for master not morty) solves the
