TODO(pldd): cheri: elf: fix pldd to compile for purecap abi
Adjust types in the E(*) structs to support capabilities. TODO: purecap pldd should refuse to deal with lp64 and ELF32 processes. the code for the 32bit case should be disabled. TODO: a correct fix requires support for all abis that can run on the same system (purecap, lp64 and ELF32 too).
