Okay, sorry for chiming in way, way late...

The reason it doesn't work is because section.mysection.start isn't seen 
by the assembler and linker as being in the same section as $.  Remember 
that outbin is really a linker.  In the case above, it's equivalent to 
$-$$, but the assembler doesn't know that, and if it had been a 
*different* section, it wouldn't have been able to resolve it.
