    Return a Tuple[str, int] e.g., ['7.1.4.34', 1806]
    The fileset bos.rte represents the current AIX run-time level. It's VRMF and
    builddate reflect the current ABI levels of the runtime environment.
    If no builddate is found give a value that will satisfy pep425 related queries

def aix_platform():
    # type: () -&gt; str
    &quot;&quot;&quot;
    AIX filesets are identified by four decimal values: V.R.M.F.
    V (version) and R (release) can be retrieved using ``uname``
    Since 2007, starting with AIX 5.3 TL7, the M value has been
    included with the fileset bos.rte and represents the Technology
    Level (TL) of AIX. The F (Fix) value also increases, but is not
    relevant for comparing releases and binary compatibility.
    For binary compatibility the so-called builddate is needed.
    Again, the builddate of an AIX release is associated with bos.rte.
    AIX ABI compatibility is described  as guaranteed at: https://www.ibm.com/\
    support/knowledgecenter/en/ssw_aix_72/install/binary_compatability.html

    For pep425 purposes the AIX platform tag becomes:
    &quot;aix-{:1x}{:1d}{:02d}-{:04d}-{}&quot;.format(v, r, tl, builddate, bitsize)
    e.g., &quot;aix-6107-1415-32&quot; for AIX 6.1 TL7 bd 1415, 32-bit
    and, &quot;aix-6107-1415-64&quot; for AIX 6.1 TL7 bd 1415, 64-bit
    &quot;&quot;&quot;
