The issue that "/usr/share is a architecture-independent location but contains architecture-dependent file", is
a "long-known problem with gobject-introspection. You'll probably find an issue or three from 10 years ago about that"
according to https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/4377

We can found issue reported years ago, gstreamer community will not handle this issue for now

And I still reject this as being an inappropriate workaround: you shouldn’t have to use update-alternatives to build something unless desperately needed.

Following the search you provided we come across https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/323 for the general issue and the accepted MR https://gitlab.gnome.org/GNOME/gobject-introspection/-/merge_requests/63 that was filed by Kang Kai from Wind River.

This is not the solution.  Putting the .gir into $libdir is the answer.  See, for example, the Debian G-I policy: https://salsa.debian.org/gnome-team/gobject-introspection/-/blob/debian/latest/debian/policy.txt?ref_type=heads.

The interesting question is why Debian doesn’t feel the need to do this.

Also what exact configuration are you replicating this in, and what is the surrounding type that contains the differing size?  I can’t replicate with qemux86 vs qemux86-64:

$ ls core2-*/gstreamer1.0/*/image/usr/share/gir-1.0/Gst-1.0.gir
core2-32-poky-linux/gstreamer1.0/1.24.12/image/usr/share/gir-1.0/Gst-1.0.gir
core2-64-poky-linux/gstreamer1.0/1.24.12/image/usr/share/gir-1.0/Gst-1.0.gir

$ diff core2-*/gstreamer1.0/*/image/usr/share/gir-1.0/Gst-1.0.gir
$

I will work on this patch on behalf of my colleague from now

reproduce steps:
1. Add in local.conf the following lines:

  MACHINE ?= "qemux86-64"

  require conf/multilib.conf

  MULTILIBS ?= "multilib:lib32"

  DEFAULTTUNE:virtclass-multilib-lib32 ?= "core2-32"

2. add lib32-gstreamer1.0-dev gstreamer1.0-dev to core-image-minimal.bb

  IMAGE_INSTALL = "packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL} lib32-gstreamer1.0-dev gstreamer1.0-dev "

3. $ bitbake core-image-minimal

Yesterday, I spent several hours trying to install GIR files into libdir instead of datadir. However, it seems this is not a straightforward task.

I sought help from the GStreamer community here:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/4383

According to the owner's response:
"This is not going to work as gobject-introspection (and meson) expect it to be installed in /usr/share. This has to be fixed in gobject-introspection first."

I realize this isn’t something that I can easily accomplish, sorry.
