Some sections have address alignment constraints. For example, if a section holds a
doubleword, the system must ensure doubleword alignment for the entire section.
That is, the value of sh_addr must be congruent to 0, modulo the value of
sh_addralign. Currently, only 0 and positive integral powers of two are allowed.
Values 0 and 1 mean the section has no alignment constraints.
