[Buildroot] Buildroot - Xenomai - error

[Laurentiu-Cristian Duca]

Hello buildroot community,

  I try to build a Xenomai 3.0.9 Linux 4.14.71-x86_64 system for qemu
using buildroot
and I am facing the below error. Is there any way to tell buildroot
to apply the patch anyway or convert this error into a warning?
Do you have any ideas how to overcome this error?
I mention that I have successfully built Xenomai 3.0.5 Linux
4.9.38-x86_64 for qemu using buildroot.
