[tremor] Tremor's use of 64-bit math

Thanks very much for your help.  Ultimately I needed to add 
a "MULTILIB_EXTRA_OPTS" line in t-arm-elf, rather than simply building a 
variant.

I haven't actually tested it on hardware, yet, but it builds fine and it 
looks as though this was exactly the solution.  Thanks again!
