Are you sure it is a good idea to try to add 32 bit executable support 
to a 64 bit target ? In the end you will need to write a 64 bit to 32 
bit linux syscall converter which would mean duplicating all the 
linux-user code of the corresponding 32 bit target (think of ioctls with 
strutures, signals frames, etc...).
