Olivier Teulière c3785555b9 Print to stderr the complete stack trace in case of exception or segmentation fault.
This feature will only be activated in debug mode, and if available on the platform.
The symbols will even be demangled if possible (i.e. if compiled with g++).

# AX_CXX_GCC_ABI_DEMANGLE

# cxxabi.h and abi::__cxa_demangle() function), define
# HAVE_GCC_ABI_DEMANGLE
