Rafael Espindola be901e2dbc Don't apply a relocation if we create a dynamic reloc. 
With RELA that is just wasteful, with REL the relocation gets applied
twice.

Rafael Espindola 01205f79a4 Start adding target abstractions. 
This is just enough to get PLT working on 32 bit x86.

The idea behind using a virtual interface is that it should be easy to
convert any of the functions to template parameters if any turns out to be
performance critical.
