Yes, we realized that upthread. It's been like that since day 1,
not something that's new in v19. I don't see that we're likely
to do anything about it: it'd require a fairly fundamental
re-architecting of our configure tests, and the end result would
only be to improve support for machines that are going to be dead
to macOS within a year.
However, it definitely is a regression that the build fails
altogether. Too bad nobody tried the x86 -> ARM case earlier.
