Please help porting psychtoolbox-3 to loong64

Hi,

I worked on the last version of psychtoolbox-3 and realised that
it does not build on loong64

   https://buildd.debian.org/status/fetch.php?pkg=psychtoolbox-3&arch=loong64&ver=3.0.22.2%2Bdfsg-3&stamp=1775643584&raw=0

Any help to fix this build would be welcome.

Kind regards
    Andreas.
