- enable thread model posix for gcc 3 which makes dwarf2 exception

handling thread safe and enables thread safety for libstdc++
- include -D_REENTRANT when -pthread cpp arg is present (needed so
boost can detect -pthread on the command line).
- bump libstdc++ major

See faq/current.html for instructions on how to correctly build
userland for this change.
