But the ELF fields are tied to the ELFCLASS of the supported ABI, not to
the register width of the machine emulation. If anything they should
become the ELF types.

(Your approach will e.g. break down for MIPS N32, where "long" is smaller
thant the register width, and the ABI uses ELFCLASS32.)

This part looks reasonable.
