64bit support for static libraries in iOS

According to Apple after June 1st, apps that are not built for 64-bit will be automatically rejected, when uploaded to app store. My app is using "Standard architectures" and BaseSDK is 8.0. With the first glance this means that the app is OK with these rules, however what happens when external libraries are not 64 bit? For example

$ lipo -info libssl.a 
Architectures in the fat file: libssl.a are: armv6 armv7 

This libssl.a files seems to be compiled for 32bit. However I do need it in my app, therefore it is linked.

Is this OK, or do I need 64bit version of my static libraries as well?
