[PATCH v2 0/2] Fit the building tools to Plan 9 environment

["KADOTA, Kyohei via GitGitGadget" <gitgitgadget@gmail.com>]

I've posted some commits for porting git to Plan 9.

This pull request is thing that cut off building scripts from #305 and is
re-constructed that.

I expect this don't change any artifacts.

differ from v1
==============

 * drop some adapters, printf, cut, expr or tar
 * drop using SHELL_PATH instead of sh
 * use real name at Signed-off-by signature

Kyohei Kadota (2):
  Fit to Plan 9's ANSI/POSIX compatibility layer
  Use $(LD) instead of $(CC) for linking the object files

     -    That haven't any commands: cut, expr and printf.
     +    tr(1) of ANSI/POSIX environment, aka APE, don't support \n literal.
     +    It's handles only octal(\ooo) or hexadecimal(\xhhhh) numbers.
      
          And its sed(1)'s label is limited to maximum seven characters.
          Therefore I replaced some labels to drop a character.
