Provisional fix for bug 3508 - Persistent storage support breaks Linux compatibility. Enables libnvmemmory.so to be built and dynamically linked on Linux and rom boot reports persistent storage image created OK, but ROM then crashes.

#include <asm/unistd.h>

extern inline volatile void exit(int status)
