Re: [Patch] BaseTools/Tests: Update GNUmakefile to use python3 variable

["Gao, Liming" <liming.gao@intel.com>]

Leif:
  OK. I will move this patch set to edk2 staging repo for people verification. 
  I will use git revert command to revert total 27 patches one by one. Then, there will be 27 commit for the revert patches. Or, one commit to combine all revert patches. One commit is enough. Do you agree it? 

  Below is the commit message for the revert patch. Could you help review it?
  Python3 migration is the fundamental change. It requires every developer to install Python3. Before this migration, the well communication and wide verification must be done. But now, most people is not aware of this change, and not try it. So, Python3 migration is reverted and be moved to edk2-staging Python3 branch for the edk2 user evaluation. 

Thanks
Liming
