Message:

Installer/linux: re-enable use of the variable KERN_DIR for building modules.
bugref:4567: Linux kernel driver maintenance

Using only the environment variable KERN_VER to decide which kernel version
to build against means that we can only use kernel headers in the default
location. This might make some things harder, so re-enable the use of
KERN_DIR in addition.
