These new functions should be added in the .map file, else it will
break the compilation in with shared_lib=y.

I see that the usage of this macro is always like this:
LOG_ERR();
ret = -1;
goto out;
What do you think of having:
#define LOG_ERR() do { \
printf("test failed at %s():%d\n", __func__, __LINE__); \
} while (0)
#define RET_ERR() do { LOG_ERR(); return -1; } while (0)
#define GOTO_ERR() do { LOG_ERR(); ret = -1; goto out; } while (0)
Then use GOTO_ERR() when appropriate. It would also factorize
the printf.
