How to git bisect run cygport ... on local clone?

Hi folks,

I have to bisect a package config failure on a small local clone.
There are only about 80 commits, and checkout and get prep make only take a 
minute until failure.

But running with SRC_URI=. or GIT_URI=. does not work!

Anyone handled such a task or have advice on doing so?

It only runs autogen.sh aclocal && autoheader && automake && autoconf: cygport 
autoreconfig does the same, so can I skip that?
