Randy Dunlap ba1029c9cb modpost: detect modules without a MODULE_LICENSE
Partially revert commit 2fa3656829 ("kbuild: soften MODULE_LICENSE
check") so that modpost detects modules that do not have a
MODULE_LICENSE.

Sam's commit also changed the fatal error to a warning, which I am
leaving as is.

This gives advance notice of when a module has no license and will taint
the kernel if the module is loaded.

This produces the following warnings on x86_64 allmodconfig:

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
