Comment (by ryandesign):

 According to [https://stackoverflow.com/questions/73714336/xcode-update-
 to-version-2395-ld-compile-problem-occurs-computedatomcount-m this], it is
 a bug in Xcode 14.0, fixed in 14.1 beta 3 and later. The solutions
 presented there are to upgrade to Xcode 14.1 or downgrade to 13.4. We have
 14.0.1 on the macOS 12 buildbot worker and I don't intend to update
 because 14.0.1 is the last version that contains the macOS 12 SDK and we
 want the SDK version to match the OS version because of the problems that
 not doing that typically causes.

 Sounds like this should be added to the port to work around the problem
 for anyone using Xcode 14.0 or 14.0.1:

 {{{
 PortGroup compiler_blacklist_versions 1.0
 }}}
 {{{
 compiler.blacklist-append {clang >= 1400 < 1400.0.29.202}
 }}}

 I could downgrade Xcode to 13.4 on the buildbot if that is strongly
 desired.
