Compare RRC_VERSION with MAKE_VERSION(x,y,z) macro to provide better SW configuration

To minimize migration effort, we follow the logic of legacy macro Rel10 and Rel14 used
for conditional compilation of current code.

In the future, they might be changed to accommodate finer software configuration, e.g.
MAKE_VERSION(12,2,0) or MAKE_VERSION(13,1,0) .... etc.
