Both alpha and sparc{32,64} (the only backends that set want_plt_sym) have
pure code in the .plt section.  It can be looked at as a table of code
snippets, all of the same size.

The .plt entries don't have symbols of their own.  They are only used to
internally resolve references to global functions.  The function symbols
always point to the real entry points.
