-- Fix cross-DLL Boost.Python exception translation on FreeBSD.
-- Move exported exception-class destructors out-of-line so the Itanium ABI
-- emits a single typeinfo/vtable instance per class in its owning shared
-- library. Without this each shared module has its own local typeinfo copy
-- and catch-by-derived-type in Python exception translators fails.
