Since v6.7 [1], the KHDR_DIR variable isn't used anymore by the kernel
selftest Makefiles to locate the kernel headers. Instead, KHDR_INCLUDES
is used to specify their location. It was only available between v6.5
and v6.7.
Keep KHDR_DIR for compatibility with v6.5 to v6.7 kernels, while
KHDR_INCLUDES is used by both pre 6.5 and post 6.7 kernels.
Let's pass it with the "-isystem" flag, as is done in the default values
used in the selftest makefiles.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
