bzImage is an x86 thing. Your questions is not really specific to
Xenomai, it is about compiling a Linux kernel for ARM. There are a lot
of resources on internet which will answer this question. For instance,
this is answered by Linux arm kernel FAQ #1:
http://www.arm.linux.org.uk/mailinglists/faq.php#f1
Or, Beagle specific instructions on Beagle wiki:
http://elinux.org/BeagleBoard#Linux_kernel

Any version should be almost Ok. Except one of the 2008 version if you
want to enable stack unwinding.

the instructions also read:
--enable-arm-mach   Select ARM machine for the       none
                    current build tree, check
                    configure --help for a list
                    of valid values.
                    Passing this option is
                    mandatory when compiling
                    Xenomai for ARM

and:
# $linux_tree = path to the target kernel sources
# $xenomai_root = path to the Xenomai sources
# $build_root = path to a clean build directory
# $staging_dir = path to a directory that will hold the installed file

Again, the issue here is about compiling a package using the autotools,
there is nothing specific about Xenomai. There is a lot of resources
about this on the web. For instance:
http://sources.redhat.com/autobook/autobook/autobook_13.html#SEC13
I even wrote a tutorial for the autotools some time ago:
