Makefile: install modules.builtin even if CONFIG_MODULES=n
Many applications check for available kernel features via: - /proc/modules (loaded modules, present if CONFIG_MODULES=y) - $(MODLIB)/modules.builtin (builtin modules) They fail to detect features if the kernel was built with CONFIG_MODULES=n and modules.builtin isn't installed. Therefore, add the target "_builtin_inst_" and make "install" and "modules_install" depend on it. Tests results: - make install: kernel image is copied as before, modules.builtin copied - make modules_install: (CONFIG_MODULES=n) nothing is copied, exit 1 Signed-off-by: Jonas Zeiger <jonas.zeiger@talpidae.net> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
