Obviously it is your choice, but this is bog standard ELF linking. In
theory even the arrays of power-of-2 sized objects should also supply an
entity size. Think __ex_table and its ilk.

The benefit of supplying an entsize is that you don't have to change the
structure of the existing code and risk breaking something in the process.
