Huacai Chen ecd9da1d05 MIPS: Loongson: Fix build error when make modules_install 
[ Upstream commit 531b3d1195d096f14e030c4b01ec3a53b80276bf ]

After commit 0e96ea5c3e ("MIPS: Loongson64: Clean up use of
cc-ifversion") we get a build error when make modules_install:

cc1: error: '-mloongson-mmi' must be used with '-mhard-float'

The reason is when make modules_install, 'call cc-option' doesn't work
in $(KBUILD_CFLAGS) of 'CHECKFLAGS'. Then there is no -mno-loongson-mmi
applied and -march=loongson3a enable MMI instructions.

To be detail, the error message comes from the CHECKFLAGS invocation of
$(CC) but it has no impact on the final result of make modules_install,
it is purely a cosmetic issue. The error occurs because cc-option is
defined in scripts/Makefile.compiler, which is not included in Makefile
when running 'make modules_install', as install targets are not supposed
to require the compiler; see commit 805b2e1d42 ("kbuild: include
Makefile.compiler only when compiler is needed"). As a result, the call
to check for '-mno-loongson-mmi' just never happens.

Fix this by partially reverting to the old logic, use 'call cc-option'
to conditionally apply -march=loongson3a and -march=mips64r2.

By the way, Loongson-2E/2F is also broken in commit 13ceb48bc1
("MIPS: Loongson2ef: Remove unnecessary {as,cc}-option calls") so fix it
together.

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.
