- Apply "Shared Makefile" style as found in [1] - Especially but not only for cross compilation: - Accept commonly used variable KDIR to specify kernel build directory - Additionally accept KERNEL_SRC (instead of KDIR) as used by PetaLinux/Yocto - Route all usual external module targets through to Kbuild - Provide "install" target as shortcut for module installation - Use $(MAKE) as recommended in [2] [1] https://www.kernel.org/doc/html/latest/kbuild/modules.html, section 3.1 [2] https://www.gnu.org/software/make/manual/make.html#MAKE-Variable, section 5.7.1.
