[PATCH] D7642: Introduce the idea of a minimum libc version

AIUI, ucrt is absolutely relevant since msvcrt itself has been split out into the ucrt.  msvcrt is the "shared" common bits, while the ucrt is more "platform" specific bits.

But really, the point is: supporting an older version with a newer compiler is what doing this the way I suggest enables.  You can use a newer compiler but still allow the generated binary to target an alternative environment.
