The backport of the UNUSED_KSYMS_WHITELIST feature to android-4.19
missed a dependency on $MODVERDIR (which is still there in 4.19), hence
causing it to un-export any symbol that is not on the whitelist, even if
it has an in-tree user.
I was _really_ close to call that a 'feature', but it wasn't exactly
intended, so I'll call it a 'bug' instead.
Kill the bugger.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
