IMHO, With all due respect, Adding CLANG to uname ? This would only
leave it to be useless information later on when we finally jettison gcc
out of base.

How about this. Create a sysctl kern.compilers and set it to be a read
only. Assign a value system to the compilers that can be used.

1 = gcc
3 = clang/llvm
5 = other

4 = gcc+clang
6 = gcc+other
8 = clang+other
9 = one strange environment.

etc... etc... etc...

Then you can still have newvers.sh generate something for inclusion that
would set the final value of that sysctl.

This should not stop the import.
