This Makefile checks that GCC is 4.9 or newer, which is redundant after
commit 76ae847497 ("Documentation: raise minimum supported version of
GCC to 5.1"), so cc-option can be removed.
Clang does not support -march=loongson3a so it needs to continue to use
-march=mips64r2, which no longer needs cc-option because all supported
clang versions recognize this flag.
-march=loonson3a can be used unconditionally with GCC because the
minimum supported GCC version has been bumped past 4.9.0, which won't
have the bug mentioned in the comment. The _MIPS_ISA macro redefinition
can be removed at the same time for the same reason.

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.
