In the future there may be more ET_* types. I don't think linking them
will be correct/intended

https://groups.google.com/forum/#!topic/generic-abi/tJq7anc6WKs "RFC: Add ET_DEBUG"
(the RFC has not been accepted but OSes can freely use ET_GNU_* )

For seabios, I sincerely wish Kevin can consider changing e_type instead
of relying a new linker option which has no use case otherwise.

ET_EXEC works for seabios is just because seabios uses a very different link
model. It ignores the symbol table and many sections which would normally appear
in a normal ET_EXEC (.hash .gnu.hash .plt .dynstr .dynsym ...)
I should add that rejecting ET_EXEC is also wish of a maintainer of the Arm proprietary linker.
