Just verified that Sun ld at least in Solaris 8 is dumb enough
not to convert UA* relocs on aligned locations into their aligned
counterparts.
Wouldn't it be easier to simply convert aligned relocs to unaligned ones
when writing them by gas if it detects misaligned location
(or, use unaligned ones internally as you had in the patch, but when
writing them into .o file convert the aligned ones from UA* to non-UA*
relocs)?
