Comment (by lukaso):

 Good call on checking `AvailabilityInternal.h`. Looks like it's ignoring
 the `SDKROOT` setting.

 This is at the top:

 {{{
 /*  DO NOT EDIT THIS FILE.

     It has been auto-edited by fixincludes from:

 "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/AvailabilityInternal.h"

     This had to be done to correct non-standard usages in the
     original, manufacturer supplied header file.  */
 }}}

 But `SDKROOT` is set to
 `SDKROOT='/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk'`
