How about:

Obsoletes: polkit < 0.112-7
(assuming this is the EVR at which the split was introduced)

https://fedoraproject.org/wiki/PackagingDrafts/MultilibTricks#Splitting_libraries_into_separate_packages

On a 32-bit system, both polkit and polkit-libs should be updated to 
polkit-0.112-7, whilst on x86_64, polkit-libs-0.112-7.i386 will obsolete 
polkit-0.112-1.i386 and the x86_64 versions will upgrade to 0.112-7 as 
expected.

Nothing arch-specific is necessary for the Obsoletes.
