It means that for example you need to cannot call block_ss code from 
common_ss without any condition, because for example usermode emulation 
targets will fail to link.  But you can freely call block_ss from files 
that are system-emulation only (such as hw/block or hw/scsi).

And on the contrary, as long as all specific_ss file implement the 
function, it is fine to call it from non-target-specific files without 
any condition.  This is what happens already with (for example) monitor 
commands that have a target-specific implementation but are present in 
all targets.
