ACK.  Just one more note to the wider audience.  I looked at QEMU's user 
mode support for nios2 on/off over the last couple years.  It never 
seemed to work well enough be able to run the GCC testsuite reliably.

As a result, my tester builds nios2 and will run the testsuite, but all 
the execution tests are only built, they're not actually run.  It's been 
fairly stable, but its not doing in-depth testing.
