Well, maybe the default option does not work, so please try
specifying --arch=x86. The error you have is not in the compiled
files, but in the Kconfig files. So, the fact that you can compile
does not really prove that prepare-kernel.sh did not fail.

Now, prepare-kernel.sh adds the scripts/Kconfig.frag file to
init/Kconfig. Kconfig.frag contains:

source "arch/@LINUX_ARCH@/xenomai/Kconfig"

With @LINUX_ARCH@ being substituted by prepare-kernel.sh. Could you
check init/Kconfig to see by what @LINUX_ARCH@ has been substituted
in your case?

If it is x86_64, then it is clearly wrong. It should be x86.
