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.
Greetings,
Henry
