Infinite recursion with dummy sound system

[AMDmi3]

I'm trying to run recent ivan on FreeBSD. With #628 change I've built it, but now it hangs after "Generating game...". gdb shows infinite recursion:

I haven't tried this, but I think there is a NOSOUND flag in the source code. As usual, there's no guarantee this will solve the problem.

If you want to use cmake for this, you'll have to get it to propagate the flag to the compiler a la WIZARD mode.

For example in the CMakeLists.txt:

option(NOSOUND "Disable sound effects" OFF)

...

if(NOSOUND)
  add_definitions(-DNOSOUND)
endif()

Then do cmake configuration step with flag -DNOSOUND=ON. Alternatively just put #define NOSOUND 1 somewhere :)

Yes, this works for me. Still it's a logic error in the code.
