    Adds support to compile QEMU with multiple tracing backends at the same time.
    For example, you can compile QEMU with:
      $ ./configure --enable-trace-backends=ftrace,dtrace
    Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.
    This patch allows having both available without recompiling QEMU.
