If any type of function granular randomization is enabled, the sympos
algorithm will fail, as it will be impossible to resolve symbols when
there are duplicates using the previous symbol position.

We could override sympos to 0, but make it more clear to the user
and bail out if the symbol is not unique.

Since we're going lots of horrendous things already, why can't we fix
this duplicate nonsense too?

I assume you mean using this new linker flag: "-z unique-symbol"
