'any old how' I think is a very old southern American thing to say, but generally never formally written (save maybe if you're writing how you're talking in a blog).
We also don't say "old", rather "ol'" so "any ol' how" would be more common to hear, but still isn't a common thing to hear much anymore, and I haven't heard anyone using it since I left the south.
As stated 'any which way' is more common and similar and also changed to "any which-a-way" when spoken.
