BBLAYERS above meta appears before meta-yocto but in BBPATH meta-yocto
appears before meta. I think meta-yocto/conf/layer.conf has

BBPATH := "${LAYERDIR}:${BBPATH}"

change it to

BBPATH .= ":${LAYERDIR}"

and if you want meta-yocto to appear before meta then rearrange
BBLAYERS above to

BBLAYERS ?= " \
 /tool/yocto/poky/meta-yocto \
 /tool/yocto/poky/meta \
 /tool/yocto/meta-openembedded/meta-oe \
 /tool/yocto/meta-xilinx \
 "

but that may not solve the problem too since now you will get

BBPATH=":/tool/yocto/poky/meta-yocto:/tool/yocto/poky/meta:/tool/yocto/meta-openembedded/meta-oe:/tool/yocto/meta-xilinx"

and it will whine about : at the beginning since that will present and
empty BBPATH when it separates them out for sanity checks.

The fix would be to see if you have : at beginning or end of BBPATH
(_after_ it has been populated) and strip it out.
