You changed so much here I can't figure out what the crash was, let's see...

Ah, the symlink fallback logic goes "this is a symlink to toybox, yes" and gets
_confused_. (Fixed it a simpler way...)

But why did it _segfault_ though? I can go "toybox toybox toybox toybox toybox",
tested that first thing years ago. Yes the _behavior_ is wrong, but that
shouldn't be a _segfault_? It's only recursing into toybox_main() 2 levels deep
before going "boing". (Is there some way to disable the stupid glibc stack dump?
It's not helpful and it means I have to scroll up to see my debug printfs. Sigh,
the FSF is almost as helpy as my cat when it comes to programming.)

Hmmm...
