This patch adds the ability to compile and install the kernel selftests into the target at /usr/lib/kselftests. The rationale behind /usr/lib is that the selftests have subdirectories where they are installed which makes them unsuitable to be placed in /usr/sbin as this would result in /usr/sbin/kselftests/x/y/z. While the selftests aren't libraries either, they don't achieve much as a standalone binary so they can be considered to be a 'library of tests' making /usr/lib sensible. The selftests require that the kernel headers be installed into the kernel build tree as some of the selftests have a hardcoded CFLAGS to include kernel headers (CFLAGS += -I../../../../usr/include/). This is most easily achieved by using the make ... headers_install inside the kernel build dir. This is likely to be a rarely used debugging/performance feature for development and unlikely to be used in a production configuration.

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 http://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 Freenode IRC.
