See Documentation/kbuild/modules.txt (under kernel sources):

--- 7.3 Symbols from another external module
        Use an extra Module.symvers file
                When an external module is built, a Module.symvers file is
                generated containing all exported symbols which are not
                defined in the kernel.
                To get access to symbols from module 'bar', one can copy the
                Module.symvers file from the compilation of the 'bar' module
                to the directory where the 'foo' module is built.
                During the module build, kbuild will read the Module.symvers
                file in the directory of the external module and when the
                build is finished, a new Module.symvers file is created
