message: Unbreak the linux bot from the previous commit.  Fred needed to use
  some of the macros from mach/exc_resource.h to decode EXC_RESOURCE,
  but that header doesn't exist on non-apple platforms and
  StopInfoMachException.cpp needs to build on those systems.
  EXC_RESOURCE won't be decoded when lldb is built on non-darwin systems.
