The EFI zboot code is not built as part of the kernel proper, like the ordinary EFI stub, but still needs access to symbols that are defined only internally in the kernel, and are left unexposed deliberately to avoid creating ABI inadvertently that we're stuck with later. So capture the kernel code size of the kernel image, and inject it as an ELF symbol into the object that contains the compressed payload, where it will be accessible to zboot code that needs it.

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.
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.
