Dear maintainers,

Compiling the weakforced failed for loong64 in the Debian Package
Auto-Building environment.
The error log is as follows,
```
......

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
