libxcb 1.12 doesn't not build without Python2

[Wayne Blaszczyk]

libxcb dependency xcb-proto has either Python2 or Python3 as a required dependency, but if only Python3 is installed then building libxcb results in the following:

  make
 Making all in src
 make[1]: Entering directory '/opt/sources/libxcb-1.12/src'
   GEN      xproto.c
   File "./c_client.py", line 1937
     after_end_of_request = '(((char*)R) + R->length * 4)'
                                                         ^
 TabError: inconsistent use of tabs and spaces in indentation
