I'm travelling and don't have hardware so I'm limited in what I can look
at right now. I suspect this workaround "works" because it makes the
"beaglebone-standard-build" extra characters on the path. I have a
feeling your -1111111 test above may have reused sstate or something
like that and given misleading results. I'd be interested in the vmlinux
file from the build above to see if the poky-111111 pathnames are in
there (they get stripped out when you create the zImage).

Cheers,
