CXXFLAGS env variable replaces compilers default optimization flags. This commit adds an explicit optimization flag. Note that this will also propagate all compiled package, but it should not produce any unwanted effects. This helps increase the performance by as much as 7x on a machine that was unable to use simulavr out of the box. Closes mkuf#284

I've been thinking a bit more about this, and I'm not sure this is a good idea after all. It might actually mess with how the simulator works on a much lower level. Gonna have to do a bit more research on this... |
