+	  This prevents Mbed TLS from linking against the following standard functions
+	  from libc: `snprintf`, `vsnprintf`, `printf`, `fprintf`, `calloc`, `free`, `setbuf`, `exit`
+	  and `time`. By default Mbed TLS will use stub functions for all these functions.
+	  These stubs are just meant to return successfully, but they don't implement
+	  the required functionality.
+	  Users can individually override each of these stubs by calling
+	  `mbedtls_platform_set_xxx()` to set the their implementation of `xxx()` function
+	  at runtime.
