Is 'PKG_CONFIG' necessary?
I see many Makefiles hard-coding 'pkg-config'.

Now that the compiler capability is evaluated in Kconfig,
this is a harder requirement.
In reality, a different compiler might be used,
and, this requirement might be loosened, but
the same compiler should be required for CONFIG_GCC_PLUGINS.

It helps external modules to be compiled for multiple kernel versions.
#if KERNEL_VERSION_CODE < KERNEL_VERSION(5, 4, 0)
code for the kernel versions older than 5.4.0
#endif
The upstream code does not do this.
But, LINUX_VERSION_CODE is actually used in many places...

This is why I think
DEBUG_CFLAGS += -gdwarf-4 (for source debug of .c files)
and
KBUILD_AFLAGS += -Wa,gdwarf-4 (for source debug of .S files)
are basically orthogonal (and they can be even controlled by
separate CONFIG options).
As stated above, DEBUG_CFLAGS += -Wa,gdward-4
does not make sense.
I am not a compiler expert, but
that is what I understood from some experiments.
Please correct me if I am wrong.

rootless builds. It also successfully found depmod
in /sbin, presumably dpkg tools automatically tweak
PATH env variable.
Maybe, the problem is when we run 'make modules_install'
for cross compilation, which we do not necessarily
require the root permission.
Users can still adjust PATH in ~/.profile, but
somebody may think breaking the legacy behavior
is annoying.
So, after some consideration, the workaround by Linus
looks good to me.

VDSO64 is only built for the 64-bit kernel, hence vgettimeofday.o is
built by the generic rule in scripts/Makefile.build.
This line does not provide anything useful.

Prefixing the file name and the line number to error messages is useful
(but should not be a part of the language specification), so now it is
implemented as a macro in scripts/Kconfig.include.
