John-Mark Gurney 6f2b769cac change td_retval into a union w/ off_t, with defines to mask the
change...  This eliminates a cast, and also forces td_retval
(often 2 32-bit registers) to be aligned so that off_t's can be
stored there on arches with strict alignment requirements like
armeb (AVILA)...  On i386, this doesn't change alignment, and on
amd64 it doesn't either, as register_t is already 64bits...

This will also prevent future breakage due to people adding additional
fields to the struct...

This gets AVILA booting a bit farther...
