It would be nice to have something that would conceptually work for
other architectures with other executable file formats.  Granted ELF is
most common, but its far from the only one.

A generic approach would allow the last-option fallback executable to be
a shell/python/perl script which could do something useful (like display
a useful message).

Well, its really a bit diseased, with lots of gristly bits and a few
unexpected tubes sticking out the side.
