Apparently from Proto-West Germanic *jehhwl, alteration of *jehwl, with irregular doubling of a velar before /w/. This /w/ then became syllabic /u/ between consonants. Neither sound change applied consistently, but both are known to have occurred in a few words. The exact same development happened to hweohhol, variant of hwēol.
