Build failed
I do everything according to the instructions, but during assembly I always get an error:

```
 implicit declaration of function 'strdup'; did you mean 'strcmp'? [-Wimplicit-function-declaration]
   60 |         elt->descURL = strdup(dev->descURL);
      |                        ^~~~~~
      |                        strcmp
/monero/external/miniupnp/miniupnpc/listdevices.c:60:22: error: assignment to 'char *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
   60 |         elt->descURL = strdup(dev->descURL);
      |                      ^
