    Pull Kbuild thin archives updates from Masahiro Yamada:
     "Thin archives migration by Nicholas Piggin.
    
      THIN_ARCHIVES has been available for a while as an optional feature
      only for PowerPC architecture, but we do not need two different
      intermediate-artifact schemes.
    
      Using thin archives instead of conventional incremental linking has
      various advantages:
    
       - save disk space for builds
    
       - speed-up building a little
    
       - fix some link issues (for example, allyesconfig on ARM) due to more
         flexibility for the final linking
    
       - work better with dead code elimination we are planning
    
      As discussed before, this migration has been done unconditionally so
      that any problems caused by this will show up with "git bisect".
    
      With testing with 0-day and linux-next, some architectures actually
      showed up problems, but they were trivial and all fixed now"
