Apart from the differences that others have mentioned, the build
machines also run a case-sensitive filesystem. That seems to be the
issue here, since the default installation of macOS (which yours likely
is) is case-preserving, but not case-sensitive, but the header is
actually

  /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/Availability.h

i.e. with a capital Availability.h, but you're including it all lower
case. That would work on a standard install, but fail on the buildbots.
