 Fix 10.6- builds with 10.14+ SDKs.

 Beginning with the 10.14 SDK, AvailabilityInternal.h uses the
 __has_include() feature without checking whether it's available.  So
 we add the usual default definition when it's not.

 Re: https://trac.macports.org/ticket/69867

 TESTED:
 Tested on 10.4-10.5 ppc, 10.5-10.6 ppc (i386 Rosetta), 10.4-10.6 i386,
 10.5-12.x x86_64, and 11.x-14.x arm64.  Tested against all 10.4-14.x
 SDKs, using the headerinfo manual test (from a subsequent commit).
 All target/SDK combinations where the SDK supports the CPU
 architecture work correctly, including all SDKs on Intel
 architectures.  Only 10.4-10.6 SDKs support ppc, and only 11.x+ SDKs
 support arm64.
