Is that linked dynamic, or did you stub out all the miscellanous junk?
Is that what the code you quote (below, which I'm cutting) is?

Why TLS?? Is there some networking going on under the hood?
Still, I would have expected all that to be done via weak symbols, so
if they aren't needed they aren't brought in. For example, there's no
need for the atexit support if the program never uses it, so with
suitable use of weak symbols and the like it should be possible for
crt0 to call on it only if it's used.
Or, at least, so I would expect. Am I missing something?
