Android x86 unity support - external .so

Since unity annonced the support of android x86, I’ve been trying to build an apk that works on x86 devices.
Sadly without success. My project have a plugin that load an external .so library. I have that dynamic lib compiled for armv7 and x86 but how can I tell unity to take that lib on armv7 and the other one on x86 ?
Most important how can I get unity to actually compile my code for x86 ?? I see nothing in unity dos nor unity interface.

Thank you very much for your help.


I’m not sure that x86 support has been released yet.
