It does not work for me.  The resulting Module.symvers is empty.

Before applying the Makefile patch, "make V=1" shows the command
to generate Module.symvers is:

  scripts/mod/modpost   -o /a/home/frowand/me/src/linux/kernel-org/build/crest/Module.symvers    -S   vmlinux.o

after applying the patch, the command becomes:

  scripts/mod/modpost   -o /a/home/frowand/me/src/linux/kernel-org/build/crest/Module.symvers    -S   -s
