conf: add C++ flags for uninative interoperatility
Create a common include file for compiler flags which allow native binaries to be interoperable on a wide range of hosts. In particular the C++ ABI is problematic so choose the CXX11 version to allow interoperation between gcc4 and gcc5 based hosts. Moving this to a common include instead of uninative.bbclass allows uninative to be configured later and used in the eSDK (where its mandatory) even if the base configuration doesn't enable uninative by default (e.g. nodistro in OE-Core).
