When building a 32 bit powerpc kernel with Binutils 2.31.1 this warning
is emitted:
powerpc-linux-gnu-ld: warning: orphan section `.branch_lt' from
`arch/powerpc/kernel/head_44x.o' being placed in section `.branch_lt'
As of binutils commit 2d7ad24e8726 ("Support PLT16 relocs against local
symbols")[1], 32 bit targets can produce .branch_lt sections in their
output.
Include these symbols in the .data section as the ppc64 kernel does.

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.
