Trying to compile Marlin 2.1.2 for Ender 3 SKR Mini v2.0 board

A more correct fix on the Marlin builder script is go to

buildroot/share/PlatformIO/scripts/marlin.py

and in line 16, replace the function with the current Marlin code

          def replace_define(field, value):
              envdefs = env['CPPDEFINES'].copy()
              for define in envdefs:
                  if define[0] == field:
                      env['CPPDEFINES'].remove(define)
              env['CPPDEFINES'].append((field, value))

The important thing is that it does .copy() in line 19.
