It is possible to add the task conditionally in an anonymous Python
method:

python () {
    if '${MACHINE}' == 'myMachineName':
        bb.build.addtask('do_mycustomtask', 'do_compile', 'do_configure', d)
}

I personally find that nicer than the if check in the function itself,
because the tasks will only show up in build logs when it actually does
something.
