Nah, the simplest thing to do is to really implement a binary format to 
store (or pipe) in_asm and out_asm traces.  Then the trace dumper could 
use all the binutils code it wants to, and would be the only thing 
requiring a v3 license.  in_asm/out_asm traces are so huge that this 
thing does have some actual benefit if somebody wants to write it.

That said, it is still nice if we can get people to agree on relicensing 
what they own, if only to help sharing code with other GPL programs. 
With the obvious exception of MIPS and linux-user, it does not seem 
impossible, though indeed hard, and it is also a good occasion to clean 
up files without a license.
