 I have no comprehensive idea about making this work in all circumstances,
 beyond fixing the check locally (which I did).

 According to this table: https://developer.apple.com/support/xcode/ Xcode
 12.4 with SDK 11.1 can be used to target 10.15.  I was just curious
 whether these kinds of patches are generally acceptable to fix SDK and
 base OS incompatibilities, or just use the corresponding SDK to avoid
 that.
