on ACCUMULO-2749 identified improved performance with better compiler optimizations for native
maps (-O3 instead of -O2).
> The native shared library is small, and enabling these additional optimizations will
not result in a significantly slower build, so I don't see any reason why we should not enable
better optimizations by default in the Makefile, if we can identify them.
