[Buildroot] [PATCH 1/1] package/kexec: fix build on pre 4.4 kernels

[Federico Pellegrin]

Hi Thomas,
This has now been merged upstream:
https://github.com/horms/kexec-tools/commit/d73822b8985b68694336cd6a1aa47fe0233b55cc

I don't know if you think it's the case to merge therefore to
Buildroot or we can wait for the next release of kexec-tools (not sure
when that could happend).

Thanks,
Federico
