TEMPLATECONF needs to be set only when you execute oe-init-build-env
to initialize the build. You don't need to permanently export it to
the environment, and can simply put it as a prefix to the command:

TEMPLATECONF=/path/to/config/template/in/some/meta-layer/ .
/path/to/oe-init-build-env /path/to/build-folder

This is awkward and not user friendly, so oe-setup-build was
developed. But it's not in kirkstone.

A command to save the active configuration to a template in a layer is
not in kirkstone either. You need to copy the files in conf/ by hand,
or you can create them yourself from nothing.

Altogether, you'll get better support for this in newer yocto
versions. We're still working on standardizing everything and closing
all the gaps.

I would recommend that you set up a scarthgap build (with just plain
poky, no other layers), and play with the tools available there to
understand better how the pieces fit together.
