kernel: lantiq: fix Module.symvers handling
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>
