Summary: `./configure` check for Carbon.h fails with CC=clang

Short testcase
When running `./configure` in a project that checks for Carbon.h, configure
tries to compile a program that contains `#include <Carbon/Carbon.h>` and a few
other includes. That program cannot be compiled with clang. A reduced test case
is attached.
This is probably related to #2427.
nico$ cat bla.c
# include <stdlib.h>
#include <Carbon/Carbon.h>
nico$ clang -fsyntax-only bla.c
