 Kbuild updates for v5.4
 
  - add modpost warn exported symbols marked as 'static' because 'static'
    and EXPORT_SYMBOL is an odd combination
 
  - break the build early if gold linker is used
 
  - optimize the Bison rule to produce .c and .h files by a single
    pattern rule
 
  - handle PREEMPT_RT in the module vermagic and UTS_VERSION
 
  - warn CONFIG options leaked to the user-space except existing ones
 
  - make single targets work properly
 
  - rebuild modules when module linker scripts are updated
 
  - split the module final link stage into scripts/Makefile.modfinal
 
  - fix the missed error code in merge_config.sh
 
  - improve the error message displayed on the attempt of the O= build
    in unclean source tree
 
  - remove 'clean-dirs' syntax
 
  - disable -Wimplicit-fallthrough warning for Clang
 
  - add CONFIG_CC_OPTIMIZE_FOR_SIZE_O3 for ARC
 
  - remove ARCH_{CPP,A,C}FLAGS variables
 
  - add $(BASH) to run bash scripts
 
  - change *CFLAGS_<basetarget>.o to take the relative path to $(obj)
    instead of the basename
 
  - stop suppressing Clang's -Wunused-function warnings when W=1
 
  - fix linux/export.h to avoid genksyms calculating CRC of trimmed
    exported symbols
 
  - misc cleanups
