This breaks:

override PYTHON := $(call get-executable-or-default,PYTHON,$(subst -config,,$(PYTHON_AUTO)))

as somehow PYTHON is expanded to a full path, yet:

override PYTHON := $(call get-executable-or-default,PYTHON,$(PYTHON_AUTO))

this works and doesn't expand PYTHON. I have no idea why, it doesn't
make sense.

Cheers,
