Package: dkms
Version: 2.8.4-2
Severity: important
Tags: patch
Control: block 984862 with -1

Third-party kernel module build systems using some kind of configure
script need to know the compiler to use (which should be the compiler
used to build the kernel) and usually fall back to CC=gcc.
The kernel compiler is available as CC inside Kbuild and we can get it
from .kernelvariables in kernel headers packaged for Debian. There may
be better and more general ways to get to this value ... but the
attached patch seems to work well to fix the current failures (packages
use gcc instead of gcc-X) and don't break other module builds.
It would be great if we can get this patch into bullseye as we can fix
at least 3 RC-buggy packages that way.
