This line is weird in multiple ways.
(CONFIG_GENERIC_CSUM) might be a typo of $(CONFIG_GENERIC_CSUM).
Even if you add '$' to it, $(CONFIG_GENERIC_CSUM) is never evaluated
to 'y' because scripts/Makefile.asm-generic does not include
include/config/auto.conf. So, the asm-generic wrapper of checksum.h
is never generated.
Even if you manage to generate it, it is never included by anyone
because MIPS has the checkin header with the same file name:
arch/mips/include/asm/checksum.h
As you see in the top Makefile, the checkin headers are included before
generated ones.
LINUXINCLUDE := \
-I$(srctree)/arch/$(SRCARCH)/include \
-I$(objtree)/arch/$(SRCARCH)/include/generated \
...
Commit 4e0748f5be ("MIPS: Use generic checksum functions for MIPS R6")
already added the asm-generic fallback code in the checkin header:
#ifdef CONFIG_GENERIC_CSUM
#include <asm/generic/checksum.h>
#else
...
#endif

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.
