boost/smart_ptr/detail/sp_counted_base_gcc_mips.hpp
contains hand-written MIPS assembly, which is not compatible
with the MIPS16e instruction set.
By not using this file in MIPS16e mode, we fallback to using
g++ 4.1+ __sync intrinsics (__sync_fetch_and_add() and
__sync_val_compare_and_swap()) which are working fine.
