Just to be clear, the 'gcc' on recent macOS has always been stub binary
that points to Apple's clang compiler and not gcc. Apple hasn't shipped an
actual gcc based compiler since before Xcode 5.0.

ps The gmp package in MacPorts relies on always building with the core2
architecture in order ship uniform packaging of gmp for all Intel based
Macs. That is why everyone sees the same glitch in Xcode 11 who is using
MacPorts.
