I tried defining a custom dep too but the error persisted. As well, I recreated
the patch using exactly your changes (for the sake of being on the same code)

Now. Even with this patch, the compile fails sometimes with:
tmp/work/raspberrypi2-poky-linux-gnueabi/userland/git-r
5/git/interface/vmcs_host/vc_vchi_dispmanx.h:72:66: fatal error:
interface/vmcs_host/wayland-dispm
anx-server-protocol.h: No such file or directory
I use autodetection of BB_NUMBER_THREADS and PARALLEL_MAKE. They end up:
BB_NUMBER_THREADS="4"
PARALLEL_MAKEINST="-j 4"
