I have found a difference between MPIDE and Arduino IDE,
The 2nd to the last line uses g++ instead of gcc. This appears to be the cause of the difference in speed.

I just added the fix to my code. I'm testing and will commit the
changes afterwards.

Example of the correct output for elf compile, where Arduino is doing floating point normally. This also makes the elf step standard to main Arduino compile.
