Hey,

Here's a patch that fixes linux-module-build-system cross-compilation. I
tested it on acpi-call-linux-module, ddcci-driver-linux, vhba-module and
rtl8812au-aircrack-ng-linux-module, seems to work fine!

Now, I'll try to rebase it on top of your patch and see if it works for
a cross-compiled system.

Thanks,

Mathieu
