So you probably used Ubuntu 14.04?

From my personal analysis I think, this is spread over several files
in OSELAS.Toolchain repository. In `rules/image-toolchain-deb.make`
IMAGE_TOOLCHAIN_DEB_VERSION_EXT is set by a function defined in
`scripts/lib/ptxd_make_debian_version_ext.sh`. This gets ${VERSION_ID}
from your build host `/etc/os-version`, which is 8 for Debian jessie,
9 for Debian stretch and probably 14.04 for the Ubuntu you are using,
so it depends on the build host. I would guess the 'bpo' means
something like 'backports', at least Debian backports uses similar
markings.

The rest of those version numbers is like this: Something creates the
file `.tarball-version`, maybe it's just included in the tarball, not
in Git repository. In `rules/image-toolchain-deb.make` the script
`scripts/setlocalversion` is called with that as a parameter, which
probably outputs some version from Git, if using the Git repo instead
of a tarball. This is assigned to IMAGE_TOOLCHAIN_DEB_VERSION in
`rules/image-toolchain-deb.make` … yes I think this is it.
