If I remember right standard ELF encodes the CPU architecture only.
Of course, most UNIX systems hide all other architectural differences
from userland code. ELF seems to have been written to only address
the problem of same-OS-different-hardware (e.g. Solaris on both sparc
and intel x86) but not the one of different-OS-same-hardware.
