This is not a bug in Xcode 11. Xcode 11 includes definitions for new flags that get picked up by Python's build, but only work on a new version of macOS. 

I guess this could be seen as a bug in macOS 10.14 (and earlier) because it ignores an unknown flag instead of returning an error.  Knowing Apple that's unlikely to get fixed, if it even is a bug (<> says that returning EINVAL is optional for an invalid value of "flags").
