This is a left-over of commit 39808e451fdf ("kbuild: do not read
$(KBUILD_EXTMOD)/Module.symvers").

Kbuild no longer supports this way.

-       Use an extra Module.symvers file

-               is generated containing all exported symbols which are

-               compilation of bar.ko to the directory where foo.ko 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 containing the sum of

        Use "make" variable KBUILD_EXTRA_SYMBOLS
