Dear maintainers,
The package libemf failed to compile loong64 rootfs environment. The
error messages are as follows,
```
...

```
After applying the attached patch, the keyman source package was
compiled successfully on my local loong64 rootfs environment.
Please consider the patch I have attached.
thanks,
