+Subject: [PATCH 1/1] Add support for nios2
+
+When compiling jack on nios2, compilation fails because NGREGS is not
+defined. Since this is only for debug output on segmentation faults, stub
+the debug print out like it's been done for other platforms before.

I've applied, but I find that this mechanism in jack2 is really done
wrongly. Instead they should use a cmake/waf/autoconf test, rather than
this never-ending list of architectures.

Thanks!
