I believe you are saying just read the path of the dynamic interpreter
and run the binary using that. If so, that does not completely address
the situation as static binaries don't have an interpreter. On FreeBSD
we have to manually brand Linux binaries such as `ldconfig' since it is a
static binary. I know someone will say to read the `.note.ABI-tag'
section. But this is not in the specification, where as `EI_OSABI' is
and that is what FreeBSD has chosen to follow to date.

To tell the truth I'm still trying to understand why it isn't incorrect
to not do so.
