The problem is not the configuration of buildroot, the problem is the
configuration of the Linux kernel. What you should do is only keep one
SOC enabled. If your processor is based on a cortex a9, look at what is
done for omap4, since the omap4 is currently the only in-tree supported
cortex a9.
For instance, the fact that you are compiling both
arch/arm/common/timer-sp.c and smp_twd.c will lead to a conflict the way
timer-sp.c is currently made. omap4 has the same problem since for
instance arch/arm/mach-omap2/timer.c is compiled both in the omap3 and
the omap4 case. So, just look at how it is done, and do it the same way.
Another simpler solution is to start from the ipipe core-3.2 branch,
which supports being built for several SOCs. However, it will require
upgrading to xenomai 2.6 branch head.
