Thanks. The problem with relying on rpm for this discovery is that this 
mechanism is not used anywhere in oe-core. I may update rpm to 4.14 and 
again break this stuff without noticing. I'd say it's better if you fix 
oe-core's code to discover those in the same way versioned libraries are 
discovered.
