Ok. Can you try the following instead of the content I gave before
KERNEL_DEFCONFIG = "odroidxu_ubuntu_defconfig"
kernel_do_configure_append() {
install -m 0644 ${S}/arch/${ARCH}/configs/${KERNEL_DEFCONFIG}
${WORKDIR}/defconfig
install -m 0644 ${S}/arch/${ARCH}/configs/${KERNEL_DEFCONFIG}
${S}/.config
}

Thank you Sathish for the quick answer.
The recipes now copies odroidxu_ubuntu_defconfig to defconfig in the
workdir, but it still seems to be ignored.
Maybe I am missing some includes to make the .config from defconfig?
Using "make odroidxu_ubuntu_defconfig" using cross compiling (followed
by "make zImage") works fine, while bitbake virtual/kernel produces some
errors which are probably due to the wrong .config.
Cheers,
Markus
