What about using the machine field of uname(2):
$ man 2 uname
Quoting from that man page:
[...] the operating system presumably knows its name, release
and version. It also knows what hardware it runs on.
Perhaps a downside, it returns the machine type as a string. Does that
do what you want?
I also find "man linux32" rather interesting:
setarch - change reported architecture in new program environment
and set personality flags
Might be useful for testing.

Both Ideas give the Kernel architecture not cpu architecture.
You can get exact cpu architecture through lshw command.
