Interesting question.
The CPython source is here: hg.python.org/cpython/
From there, select branches, 2.7, and browse.
From there, Python/bltinmodule.c has source for non-class builtin x
under the name builtin_x.
builtin_dir is a thin wrapper around PyObject_dir().
That is included by python.h, which includes nearly everything,
including object.h.
With a little more looking, the code for PyObject_dir is in
Objects/object.c after some helper functions that it uses.
That calls helper _dir_object(), which calls a more specialized helper
if ob.__dir__ does not exist.
Even if this does not help you, I learned something about the source
tree in tracking down the answer.
