During filesystem construction the system uses dependencies to decide what to
install.  If you build a 32-bit connman-gnome and it requires other 32-bit
libraries the dependency scanner will either pick them up and install them, or
error due to missing dependencies.

In the manual case you would use "rpm -Uhv <path>" manually specifying which one
you want.  RPM will detect a multilib package and will allow installation of
both versions.  (Note always use rpm -U and not rpm -i..  rpm -i just blindly
installs the software with no checking if an existing version exists.)

No specific order should be necessary on a multilib system.  As long as the end
dependencies are satisfied the resulting filesystem will work.  (Exceptions to
this are when there are pre and post install scripts that have their own unique
dependencies.. but those are not the normal case for OE-Core/Yocto.)
