Subject: linux-next: build failure after merge of the kbuild tree

Hi all,

After merging the kbuild tree, today's linux-next build (sparc64
defconfig) failed like this:

sparc64-linux-ar: unrecognized option '--thin'
Usage: sparc64-linux-ar [emulation options] [-]{dmpqrstx}[abcDfilMNoOPsSTuvV] [--plugin <name>] [member-name] [count] archive-file file...
       sparc64-linux-ar -M [<mri-script]
 commands:
  d            - delete file(s) from the archive
  m[ab]        - move file(s) in the archive
  p            - print file(s) found in the archive
  q[f]         - quick append file(s) to the archive
  r[ab][f][u]  - replace existing or insert new file(s) into the archive
  s            - act as ranlib
  t[O][v]      - display contents of the archive
  x[o]         - extract file(s) from the archive
 command specific modifiers:
  [a]          - put file(s) after [member-name]
  [b]          - put file(s) before [member-name] (same as [i])
  [D]          - use zero for timestamps and uids/gids
  [U]          - use actual timestamps and uids/gids (default)
  [N]          - use instance [count] of name
  [f]          - truncate inserted file names
  [P]          - use full path names when matching
  [o]          - preserve original dates
  [O]          - display offsets of files in the archive
  [u]          - only replace files that are newer than current archive contents
 generic modifiers:
  [c]          - do not warn if the library had to be created
  [s]          - create an archive index (cf. ranlib)
  [l <text> ]  - specify the dependencies of this library
  [S]          - do not build a symbol table
  [T]          - make a thin archive
  [v]          - be verbose
  [V]          - display the version number
  @<file>      - read options from <file>
  --target=BFDNAME - specify the target object format as BFDNAME
  --output=DIRNAME - specify the output directory for extraction operations
  --record-libdeps=<text> - specify the dependencies of this library
 optional:
  --plugin <p> - load the specified plugin
 emulation options: 
  No emulation specific options
sparc64-linux-ar: supported targets: elf64-sparc elf32-sparc elf64-little elf64-big elf32-little elf32-big srec symbolsrec verilog tekhex binary ihex plugin

Caused by commit

  833726f654c7 ("kbuild: replace deprecated T option with --thin for $(AR)")

sparc64-linux-gcc (GCC) 11.1.0
GNU ld (GNU Binutils) 2.36.1

I have reverted that commit for today.
