Hi Ram Pai.

In principle what your patch does is a simple port-processign of
Module.symvers.
Insead of introducing another step in the buildprocess then for this
functionality we should just call your script direct.
This is not something the average users will do often, so having to
type:
./scripts/export-report.pl

And then let the perl script pick up default values for where to find
*.mod.c files and Module.symvers.

Thoughts?
