[Tracing] Deciding the Yaml configuration for barectf input

[Vidushi Vashishth]

Hi!

Quick question. I tried to modify the printk trace generator to print the
output traces into a text file instead of the console. On running the
normal link and trace linker commands there are no compilation errors.
However when I run the application executable using GDB it says [Inferior 1
(process 42000) exited normally].

This is what I am doing to the code section of the rtld-print.ini's printk
generator:

static inline void rtld_pg_printk_entry(const char* func_name,
                                        void*       func_addr)
{
  FILE* fp = fopen("trace.txt", "a");
  fprintf (fp, ">>> %s (0x%08x)\n", func_name, func_addr);
  fclose(fp);
}

Is there something wrong with this approach?
