Linus Torvalds b753101a4a Kbuild updates for v5.7 (2nd) 
- 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
