I thought the stack is reset by the startup stub?

At one point, we need to rewrite the bootstrap relocation in something
else besides C, but I suppose we can just stick in
-fno-tree-loop-distribute-patterns today.

Not sure if I understand the question.  The memset is likely redundant
on Linux because the stack is fresh and unperturbed.  If the startup
stub allocated it, clearing it wouldn't be necessary.  But the
situation is a bit iffy at the C level.
