cxx.cc: Fix dynamic initialization for static local variables
The old implementation for __cxa_guard_acquire did not return 1,
therefore dynamic initialization was never performed.
If concurrent-safe dynamic initialisation is ever needed, CXX ABI
must be followed when re-implementing __cxa_guard_acquire (et al.)
