libstdc++: Fix -Wunused-function warning in src/c++11/debug.cc

The only remaining use of print_raw is conditionally compiled, so when
libstdc++ i built without debug backtrace support, there's an unused
warning function for it. Move it inside the conditional block.

libstdc++-v3/ChangeLog:

	* src/c++11/debug.cc (print_raw): Move inside #if block.
