I wouldn't expect `GIT_URI=.` to work unless the cygport file is in
the root of the source directory you're working in, and even then I'm
not sure it wouldn't cause problems.
I'm currently doing something similar with the git codebase itself.
The changes I needed to make to the .cygport file were thus:
1. Stop setting SRC_URI and SRC_DIR
2. Add the following:
GIT_URI=/home/adam/git
GIT_REV="$(git -C /home/adam/git rev-parse HEAD)"
inherit git
3. Optionally change the definition of VERSION; for git, I've set it
to the following, which mimics the behaviour when building from git
itself.
VERSION="$(git -C /home/adam/git describe | sed 's/-/./')
I haven't (yet) tried making this work with `git bisect run`, but I'd
expect that to be straightforward once you have the builds working or
failing as desired when running the cygport commands manually.

I don't see why not, although it would obviously depend on the
specific problem you're seeing. If the cygport script is simple
enough, it might be easier to bisect by just running the build
commands directly rather than using cygport.
