linux-user: Remove ELFLOAD32.

Browse source 
The ABI-specific types used by linux_binprm and image_info
are different after forcing TARGET_ABI32 on.  Which means
that the parameters that load_elf_binary_multi sees are not
those that loader_exec passed.  This is inherently broken
and is more trouble than it's worth fixing.
