04f2902d9f Future safety in checking ELF header.
If we should use further fields in the e_ident array in the ELF header

that non-optional features indicated by nonzero values are not go
unnoticed when using an old dynamic linker.

d8c47894ca Extended ELF ABI version handling only for Linux.
If the OSABI is generic we should not allow the ABI version to be nonzero.
Move all the new functionality into Linux-specific files.
