The nolibc testsuite wants to generate an initrams without linking it into the kernel for which it needs access to gen_init_cpio. Add a new toplevel target for it so it can be built standalone. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> --- Kbuild maintainers: If there is a way that does not require modification of the toplevel Makefile that would be nice, too. I followed the example of the "scripts_unifdef" target. --- Makefile | 4 ++++ 1 file changed, 4 insertions(+)
