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
