The distribution is Linaro:

    $ lsb_release -a
    No LSB modules are available.
    Distributor ID:    Debian
    Description:    Debian GNU/Linux 8.4 (jessie)
    Release:    8.4
    Codename:    jessie

And the GCC version is:

    $ gcc --version
    gcc (Debian/Linaro 4.9.2-10) 4.9.2

I verified there are no outstanding updates available.
