That's not correct, or at least not useful. The architecture is what
uname(2) reports, and if the system is currently running a 32-bit
kernel, it will be "i686" no matter if the processor is 64-bit capable.
The information about the latter is in the "Flags:" field of the lscpu
output. If it contains the "lm" (for "long mode[1]") flag, you have an
x86_64 processor.
