 However, the SymCC compiler needs to be made aware of the location of the runtime that it should instrument against.

 The only difference between using SymCC and SymQEMU should be the binary that represents the target:
 In the case of SymCC it will be the binary that was build with instrumentation and with SymQEMU it will be the emulator binary (eg. `x86_64-linux-user/symqemu-x86_64`), followed by your uninstrumented target binary and its arguments.
