[Buildroot] Buildroot - udev : undefined reference to `accept4'

[Vellemans, Noel]

Hi Peter,

You are right, uclibc-patch did not solve, and indeed newer ARM-kernel
solves the problem. 

Thanks,
Noel

Your kernel headers (and runtime kernel) are too old. Udev needs
accept4() which was added to the kernel relatively recently (2.6.36 for
ARM).

That doesn't help as udev NEEDS accept4.
