in oe-core we munge CROSS_TARGET_SYS_DIR and append PN to it, this 
should be considered in gcc-cross-kernel.inc

you need couple of changes

change the install command like below in gcc-cross-kernel.inc

install -m 0755 xgcc 
${D}${STAGING_DIR_NATIVE}${prefix_native}/bin/${TARGET_PREFIX}gcc-${PV}

secondly you need to inform kernel recipe of this new location of toolchain

so in you kernel recipe somewhere patch the below code

PATH_prepend = "${STAGING_BINDIR_TOOLCHAIN}.gcc-cross-kernel:"

Thanks
