If an external module uses exported symbols from another external module, Kbuild needs to have full knowledge of all symbols to avoid spitting out warnings about undefined symbols. Use PKG_EXTMOD_SUBDIRS to point to the build directory which contains the Module.symvers. Pass KERNEL_MAKE_FLAGS to the external module build, to inject KBUILD_EXTRA_SYMBOLS. KBUILD_EXTRA_SYMBOLS holds a space separated list of Module.symvers, which list all exported symbols. Signed-off-by: Mathias Kresin <dev@kresin.me>
