People use the Unity editor to build a data file that these binaries know how to run. The Editor could be compiled with a later compiler, but we need our runtimes to target ancient systems as well (when to up the requirements of any version is a long debate; we're just now dropping PPC). The editor also has an embedded Runtime (so people can test their games).

As a follow up, it look like everithing end up calling NSVersionOfLinkTimeLibrary() which is defined in the following file:
http://opensource.apple.com/source/dyld/dyld-195.5/src/dyldAPIsInLibSystem.cpp
As you can see, this function has a major flaw, as it check version against the executable only.
A tricky way to fool the system can be to move all you application code into a framework, and have a simple launcher compiled on 10.7 that just call a 'main' entry point in your framework.
