 FWIW I find the choice of ELF32 correct for an ABI (such as the x86-64 
target's x32 ABI I believe is) that has a 32-bit pointer size, as all ELF 
structures are then consistently 32-bit as well; and as a side effect you 
also have no technical means to request an invalid address space mapping.  
The same choice has been also earlier made for the MIPS target's n32 ABI.
