Great.

It would be nice to find the minimal patch which works.
Could anyone try the attached patch?

It seems that the code is using the pagesize (which is different on
loong64) as a poor proxy for architecture detection. Maybe somebody
should tell them to enable the library or not based on the library
actually existing for such architecture or not.

Thanks.
