gen-hyprel is, for better or worse, a native-endian program:
it assumes that the ELF data structures are in the host's
endianness, and even assumes that the compiled kernel is
little-endian in one particular case.
None of these assumptions hold true though: people actually build
(use?) BE arm64 kernels, and seem to avoid doing so on BE hosts.
Madness!
In order to solve this, wrap each access to the ELF data structures
with the required byte-swapping magic. This requires to obtain
the kernel data structure, and provide per-endianess wrappers.
This result in a kernel that links and even boots in a model.

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.
