Kbuild updates for v5.7 (2nd)

Browse Source 
- raise minimum supported binutils version to 2.23
 
  - remove old CONFIG_AS_* macros that we know binutils >= 2.23 supports
 
  - move remaining CONFIG_AS_* tests to Kconfig from Makefile
 
  - enable -Wtautological-compare warnings to catch more issues
 
  - do not support GCC plugins for GCC <= 4.7
 
  - fix various breakages of 'make xconfig'
 
  - include the linker version used for linking the kernel into
    LINUX_COMPILER, which is used for the banner, and also exposed to
    /proc/version
 
  - link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y,
    which allows us to remove the lib-ksyms.o workaround, and to
    solve the last known issue of the LLVM linker
 
  - add dummy tools in scripts/dummy-tools/ to enable all compiler
    tests in Kconfig, which will be useful for distro maintainers
 
  - support the single switch, LLVM=1 to use Clang and all LLVM utilities
    instead of GCC and Binutils.
 
  - support LLVM_IAS=1 to enable the integrated assembler, which is still
    experimental

These two variables allow to override the user@host string displayed during
boot and in /proc/version. The default value is the output of the commands
whoami and host, respectively.
LLVM
----
If this variable is set to 1, Kbuild will use Clang and LLVM utilities instead
of GCC and GNU binutils to build the kernel.

LLVM Utilities
--------------
LLVM has substitutes for GNU binutils utilities. These can be invoked as
additional parameters to `make`.
LLVM has substitutes for GNU binutils utilities. Kbuild supports `LLVM=1`
to enable them.
make CC=clang AS=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \\
OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump OBJSIZE=llvm-objsize \\
make LLVM=1
They can be enabled individually. The full list of the parameters:
make CC=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \\
OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump OBJSIZE=llvm-size \\
READELF=llvm-readelf HOSTCC=clang HOSTCXX=clang++ HOSTAR=llvm-ar \\
HOSTLD=ld.lld
Currently, the integrated assembler is disabled by default. You can pass
`LLVM_IAS=1` to enable it.

# Staring v4.18, Kconfig evaluates compiler capabilities, and hides CONFIG
# options your compiler does not support. This works well if you configure and
# build the kernel on the same host machine.
#
# It is inconvenient if you prepare the .config that is carried to a different
# build environment (typically this happens when you package the kernel for
# distros) because using a different compiler potentially produces different
# CONFIG options than the real build environment. So, you probably want to make
# as many options visible as possible. In other words, you need to create a
# super-set of CONFIG options that cover any build environment. If some of the
# CONFIG options turned out to be unsupported on the build machine, they are
# automatically disabled by the nature of Kconfig.
#
# However, it is not feasible to get a full-featured compiler for every arch.
# Hence these dummy toolchains to make all compiler tests pass.
#
# Usage:
#
# From the top directory of the source tree, run
#
# $ make CROSS_COMPILE=scripts/dummy-tools/ oldconfig
#
# Most of compiler features are tested by cc-option, which simply checks the
# exit code of $(CC). This script does nothing and just exits with 0 in most
# cases. So, $(cc-option, ...) is evaluated as 'y'.
#
# This scripts caters to more checks; handle --version and pre-process __GNUC__
# etc. to pretend to be GCC, and also do right things to satisfy some scripts.
# Check if the first parameter appears in the rest. Succeeds if found.
