wrong bss/sbss section choosen when multiple commons merged

I think you probably want to use the section of the _smaller_ symbol.
That is, you want the symbol to be in sbss rather than in bss, because
one of the object files will assume that the symbol has been placed in
the sdata section (since it was small enough).
