I don't think that's the case; for example, a lot of embedded Linux 
systems do use shared libraries and third party apps that depend on 
those libraries, so compatibility does really matter.  But, those 
systems are small enough that lots of the system is generally 
cross-compiled.

That said, I think Ian's right; it's better to accept the ABI breakage 
than to have cross- and native-compilation differ.  The latter problem 
is just too horrid.
