 For the record RV32 and RV64 QEMU ULPS results (obtained in the Linux 
user emulation mode) match each other in my setup.  However those don't 
match RV64 results obtained with my HiFive Unleashed hardware, and then 
those don't match our existing RV64 results, so I guess they will have to 
be regenerated for the upcoming release.

 I'll leave this change up to Joseph to ack, as he's the expert in this 
area.
