This is not related, but you should upgrade your I-pipe patch, there are at
least two candidates for 2.6.24:
http://download.gna.org/adeos/patches/v2.6/powerpc/older/adeos-ipipe-2.6.24-powerpc-DENX-2.1-04.patch
http://download.gna.org/adeos/patches/v2.6/powerpc/older/adeos-ipipe-2.6.24.6-powerpc-DENX-2.4-03.patch

DENX-2.6.24-stable is fairly outdated as well; DENX-v2.6.26-stable or maybe .27
would be better. I suspect the Xenomai distro you are using is outdated as well,
 probably 2.4.3. 2.4.6.1 is the current -stable, and 2.4.7 is pending for release.

There is no mpc5200_defconfig in DENX-v2.6.24-stable; the proper defconfig is
lite5200_defconfig. Is mpc5200_defconfig a file of yours?

$ git checkout -b 2.6.24-xeno origin/DENX-v2.6.24-stable
$ $XDIR/scripts/prepare-kernel.sh --arch=powerpc --linux=.
$ make ARCH=powerpc CROSS_COMPILE=ppc_6xx- lite5200_defconfig
<edit config as needed>
$ make ARCH=powerpc CROSS_COMPILE=ppc_6xx-

If you really want to build from the user-space Xenomai tree instead, then refer
to §1.4 in README.INSTALL.
