CTF vs dwarf4

[Pedro Giffuni]

Hello;

Just thought I'd point out, for those not following toolchain@, that 
there are issues with newer compilers using dwarf4 by default[1].

It looks like instead of waiting for the elftoolchain project to catch 
up with the dwarf standard we could be using dwarf support from  LLVM 
instead though [2].

Apparently the linux dtrace port is having similar issues.  Another task 
for the Dtrace TODO list I guess, but perhaps the Illumos guys following 
the list may have some input.

Regards,

Pedro.
