[RFC] N_BNSYM/N_ENSYM stabs

[Devang Patel]

Geoff has committed patch that requires new cctools, so now flood gate 
is
open :-).

Newer Darwin cctools support dead code stripping. To strip debugging 
info
stabs while removing function body, linker needs N_BNSYM/N_ENSYM stabs
around stabs of each function. Older darwin linker also uses them to 
remove
duplicate coalesced symbols for C++ templates.

Is it a good idea, if I propose a patch to generate these new stabs?.
According to our GDB folks, no GDB change is required.

Thanks,
