It is so for now. I hope that recursive behaviour will not be 
interesting for iproute  Makefile. If Makefile wants to pass the 
variable recursively it will do it with my replacement too, if it 
doesn't but a new variable with the same name appears in child directory 
- well, it deserves manual inspection anyway. Probably you are right, in 
disasterous case of iproute having recursive Makefile system with own 
SBINDIR declared in every Makefile your solution will work better.

OK, I attach default.nix for your way and with one bug fixed - it now 
fixes all hash-bang-bash extries, not only those needed for building 
'ip' itself.
