No what you need to do is generate a dynamically loaded executable
that doesn't have a 'NEEDED' entry for lib.so.
However I can't seem to persuade ld to do that!
cc -O2 x.c /usr/lib/libc.a -o y
Generates a binary with no unresolved symbols (and it has an ___start)
but unfortunately it still has a 'NEEDED' entry for libc.
(I haven't tried running it under a copy of ld.elf_so that fails
to load libc (yet)).
