Comment (by kencu):

 It might also have something to do with this:
 {{{
 /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
 }}}

 That is going to be a symlink to the MacOSX11.0.sdk, and so it will try to
 build ARM (as it sees support in that SDK).

 So we need to enable this test for > darwin18 not 19 I suspect.

 We need to be able to force these builds (qt5 15.1 as well) to use the OS-
 specific SDK (10.15) and we are not seemingly doing that -- although the
 compiler_rt part of this tends to do it's own thing with respect to
 searching out SDKs, to be honest...
