That is the version number you get if you run "clang -dumpversion". gcc 
compatibilty at its worse.

And this is evalutated by  gcc.jam which is inherited by clang-*.jam...

One way dould be to change the clang toolset to parse "clang -v"

and use this. Or get the clang devs to report the "real" clang version with "-
dumpversion" or something different switch.
