Unfortunately these commits:
2834c3e Add support for generating a systemtap tapset static probes
4addb11 Add a DTrace tracing backend targetted for SystemTAP compatability

seem to have broken building on x86:
 git clone git://git.qemu.org/qemu.git
 cd qemu
 ./configure
 make

fails with
  LINK  i386-softmmu/trace
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../../lib/crt1.o: In
function `_start':
(.text+0x20): undefined reference to `main'
collect2: ld returned 1 exit status

Incidentally, although trace.c is autogenerated, if you delete it and
then type make this does not cause it to be regenerated, which
seems wrong to me.
