well, if the binary contains machine instructions
not available on the executing host, the program 
will most probably fail/abort/hang;
if you compile explicitly for a certain host higher
than i386 you can never be sure to be able to run
the prog on another machine. AFAIK it can also happen
that a prog compiled for a i486 cannot be run on an
i586 because of some machine instructions only 
available on the 486.

So you may be lucky and ther prog runs even on a lower
host but you shouldn't rely on it.
