program header size now, because we cannot change it later --
that could alter section placements. Notice the A8 erratum fix
ends up requiring the section addresses to remain unchanged
modulo the page size. That's something we cannot represent
inside BFD, and we don't want to force the section alignment to
be the page size. */
