build_ext calls distutils.sysconfig.get_python_inc() wich looks for
Modules/Setup.dist or  Modules/Setup.local in the current directory
to decide if we are trying to build Python itself, to behave slighlty
differently.

So if you are in a python checkout it's  the case. This is not really
robust, but explains why you have that behavior.

I consider the whole  distutils.sysconfig module quite messy, and I
have proposed in python-ideas its removal in favor
of a standalone sysconfig module in the stdlib that would provide
static information on how Python was build
(eg like a Makefile) + a few helpers
