Comment (by rwbarton):

 You probably have a non-Apple (e.g., homebrew) `clang` installed then,
 that doesn't know about `.macosx_version_min`.

 The use of `clang` (whichever one is first on your PATH) is hard-coded. I
 would guess that the original issue that led to this situation (#5636) is
 no longer relevant, but I don't know whether using the configured C
 compiler is more likely to work here in general.
