kbuild: Add new Kbuild variable KBUILD_EXTRA_SYMBOLS
This patch adds a new (Kbuild) Makefile variable KBUILD_EXTRA_SYMBOLS. The space separated list of file names assigned to KBUILD_EXTRA_SYMBOLS is used when calling scripts/mod/modpost during stage 2 of the Kbuild process for non-kernel-tree modules.
