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
