What is 64-bit code, and why do you need to know in your program? Both are serious questions, and LONG_MAX/ULONG_MAX, CHAR_BIT and AC_CHECK_SIZEOF for int, long, or a pointer type, may be part of the answer to your question. Of course, many programs don't need to know or check for any of this at all and are still portable to "64-bit" systems, or even systems with 48 bit types, which is Good. Checking $host is likely not what you would want, as for ./configure CC='gcc -m32' on x86_64-unknown-linux-gnu, it may match.
