Summary: "port install ucl" fails due to problem with confdefs → ucl @1.03: error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))'

The config.log shows a problem we see with lots of software these days: 

conftest.c:29:7: error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration]
      exit(2);
      ^
conftest.c:29:7: note: include the header <stdlib.h> or explicitly provide a declaration for 'exit'

Until we resolve these issues, you can work around them by downgrading to Xcode 11 and the Xcode 11 version of the command line tools. (In Xcode 12, Apple made the implicit declaration of functions an error instead of a warning as it was before.)
