That is really odd. I'll be interested to hear how that happened. I just
did a test and it points to where I expect:

  [/home/bruc...poky/build]> bitbake -e core-image-minimal | grep 
STAGING_KERNEL_BUILDDIR
# $STAGING_KERNEL_BUILDDIR
STAGING_KERNEL_BUILDDIR="/home/bruce/poky/build/tmp/work-shared/qemux86-64/kernel-build-artifacts"
