Thank you for the feedback. I have experienced this issue while building
branch master on Ubuntu 16.04. As discussed in the IRC channel on Friday
the same issue has been reproduced in the CI, Job #78257653 triggered by
Thomas Petazzoni: https://gitlab.com/buildroot.org/buildroot/-/jobs/78257653

I have noticed that the same fix has been already applied to
raspberrypi3_64_defconfig. I hope my patch will be merged to prevent
this issue in future for raspberrypi3_defconfig.

Thanks,
Leon
