An archaic or dialectal form meaning 'anywhere' or 'in any place or direction.'
From Middle English 'aiware' or 'aywhere,' combining 'ay' (ever) or 'a' (one) with 'where.' This is a historical variant that faded as Modern English standardized its adverbs of location.
Words like 'aywhere' show us that English used to have way more flexibility—you could basically stick 'a' or 'ay' in front of words to mean 'any-' of that thing, but we've mostly standardized and lost these variant forms!
