This patch requires that /sbin/depmod is installed and installable on the build host. But not all build hosts for cross compiling Linux are Linux systems and are able to provide a working port of depmod, especially at the file patch /sbin/depmod. I use, for example, a Darwin system to cross compile Linux and I run depmod -a on the embedded system once, after installing a new Linux kernel there. I have no problem with seeing a warning, but aborting the build process is IMHO a bad idea since the previous behaviour didn't harm many people as far as I see. Probably 99% of people compiling Linux kernels do that on Linux and 99% of those have depmod installed for optimal operation of their build host. So IMHO printing the warning is good enough.
