If this file is different on across architectures then it shouldn’t be installed into $datadir, but $libdir.  Abusing multilib_scripts like this is not correct.

But /usr/share/gir-1.0/Gst-1.0.gir do differs across architectures, and it is not in $libdir but $datadir 
if we shouldn't use multilib_scripts, then what we should do in this kind of situation?

Talk to upstream, either it should be in datadir and not contain architecture-specific information, or it should be moved to libdir.

Hi, Ross

I have created an issue in gstreamer project:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/4377
 
and maintainer has replied:
".gir files are in general not platform-independent and there's not much we can do about that."
 
So, seems upstream will not handle this issue...

Best regards
