  You need to build and install mtrace:
    git+ssh://amsterdam.csail.mit.edu/home/am6/mpdev/qemu.git -b mtrace

-  #define MTRACE 1 in param.h
+  #define MTRACE 1 in param.h  (for qemu!)
  If mtrace isn't cloned next to the xv6-scale repository, then set
  QEMUSRC in config.mk to the directory containing mtrace-magic.h.
  Set MTRACE in config.mk to the mtrace QEMU binary's path.
