You pointed at multi-arch.  Yes, GDB refuses non-multi-arch targets.  As 
much as anything it is because non-multi-arch targets have a 
significantly higher maintenance overhead and there is little benefit in 
having the GDB community take on the extra burdon of maintainging such 
code.  On the other hand people are free to develope non-multi-arch 
targets and distribute them.  The code might work but that certainly 
doesn't make it either correct or suitable for integration into GDB.

enjoy,
Andrew
