* The license cheksum is changed becuase a new line is added:
  Copyright (C) 2001-2017 The strace developers.

* Remove use-asm-sgidefs.h.patch, it doesn't check sgidefs.h any more, it was
  use for building on mips, I checked it built well.

* Update Makefile-ptest.patch and disable-git-version-gen.patch.
