On my system 'uname -p' produces "unknown"; `uname -m` is the canonical
method of telling you what arch the kernel you're running is.

Another one you can use is 'file' on your libc;

denix:~$ file -L /lib/libc.so.6
/lib/libc.so.6: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped
