Are those file actualy architecture dependend and why so?

The right way to solve this is to compile the lib with multiarch
directories on all archs.
What you are missing is that the ia32-libs package is build buy taking
the i386 debs, unpacking them, some patching and repacking the thing
as ia32-libs. There is nothing getting compiled.
