You can make things quite a lot better by including these lines in your
program:
exit() { }
abort() { }
atexit() { }
void *__libc_stack_end;
The latter is really a granularity problem with libc but the first three are
probably to be expected. There's no easy way to avoid that excess code being
linked in without imposing additional runtime overhead.
