Are you still having trouble with this?  I tried building iproute2 (in
latest PetaLinux SVN trunk) and see a completely different error:

In file included from
/home/jwilliams/PetaLogix/petalinux/trunk/software/petalinux-dist/linux-2.6.x/include/asm-generic/bitops.h:12,
                 from
/home/jwilliams/PetaLogix/petalinux/trunk/software/petalinux-dist/linux-2.6.x/include/asm/bitops.h:24,
                 from ../include/utils.h:5,
                 from utils.c:33:
/home/jwilliams/PetaLogix/petalinux/trunk/software/petalinux-dist/linux-2.6.x/include/asm-generic/bitops/atomic.h:
In function `set_bit':
/home/jwilliams/PetaLogix/petalinux/trunk/software/petalinux-dist/linux-2.6.x/include/asm-generic/bitops/atomic.h:69:
error: `BITS_PER_LONG' undeclared (first use in this function)

basically, iproute2/include/utils.h is including <asm/types.h> and asm/bitops.h>

in microblaze, we use asm-generic/bitops, which requires the macro
BITS_PER_LONG to be defined.  This is definied in asm/types.h, but
inside and #ifdef __KERNEL guard.  including this stuff from userspace
just doesn't work.

John
