Appears to fix #500. Extensive writeup there.
Also removed a couple of compiler flags that were not needed:
-mtune=cortex-m4supposedly subsumed by-mcpu=cortex-m4-mlong-callshandles calls further away than 64MB. That's not an issue for us! Removing this saves about 12.5kB (!) in M4 image.Also turned on
-fltoinDEBUG=1builds to make it more likely we'll hit issues, but made it easy to comment out.
