Parisc overrides 'nm' with a shell script. I was hit by a false-positive
error of $(NM) because this script returns the exit status of grep
instead of ${CROSS_COMPILE}nm. (grep returns 1 if no lines were selected)
I tried to fix it, but in the code review, Helge suggested to remove it
entirely. [1]
This script was added in 2003. [2]
Presumably, it was a workaround for old toolchains (but even the parisc
maintainer does not know the detail any more).
Hopefully, recent tools should work fine.

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.
