OK, so I took another look and the only validation that seems kinda
related is the one that detects the wrong ELF class.  That too is not
specifically a protection against invalid ELF; just not somthing this
linker runs.  So I guess it is easy to claim that ld.so assumes that
the ELF is valid.  I withdraw my patch if the general idea of allowing
the linker to do arbitrary things or crashing on invalid ELF is
acceptable.
