Any C programming technique apart from using this /proc/cpuinfo

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.
