> 
> /proc/version_signature is the version for the host machine, but in e.g., chroots,
> this does not necessarily match that DPDK is built for. DPDK will then build for the
> wrong kernel version - that of the server, and not that installed in the (build)
> chroot.
> 
> The patch uses utsrelease.h from the kernel sources instead and fakes the
> upload version.
> 
> Tested on a server with Ubuntu 12.04, building in a chroot for Ubuntu 14.04.
