Hi Guix,

I have a bad day.  After the upgrade to glibc 2.26 none of the
Guix-installed software runs on the HPC cluster running CentOS 6.8.

The glibc 2.26 expects a minimum kernel version of 3.x on x86_64, but
CentOS 6.8 only comes with a heavily patched 2.6.32.

The NixOS developers patch glibc to make sure that all software still
runs on Linux 2.6.32:

    https://raw.githubusercontent.com/NixOS/nixpkgs/master/pkgs/development/libraries/glibc/allow-kernel-2.6.32.patch

Can we please also apply this?  Without this Guix on HPC is pretty much
dead at the MDC.
