Dear maintainers,

Compiling the weakforced failed for loong64 in the Debian Package 
Auto-Building environment.
The error log is as follows,
```
......
/usr/bin/ld: trackalert.o: in function `std::_Rb_tree<std::pair<Netmask, 
bool>*, std::pair<Netmask, bool>*, std::_Identity<std::pair<Netmask, 
bool>*>, std::less<std::pair<Netmask, bool>*>, 
std::allocator<std::pair<Netmask, bool>*> 
 >::_M_erase(std::_Rb_tree_node<std::pair<Netmask, bool>*>*)':

The full build log can be found at 
https://buildd.debian.org/status/logs.php?pkg=weakforced&arch=loong64.

Please consider the patch I attached.
Append -latomic to LDFLAGS on loong64, and weakforced was built 
successfully on locally.
Your opinions are welcome.

Best regards,
Dandan Zhang
