The autoconf documentation does not specify 'no' as a magic value,
which means that the accidental presence of a file called 'no' would
pick up the file.
Wouldn't it be safer/cleaner to use CONFIG_SITE=/dev/null?
Note that I have not tested if this actually works, just a thought.

Best regards,
Thomas
