lscpu: last cpu(cluster) is not displayed

[MatejMagat305]

I have same problem as util-linux/util-linux#3062, but on termux "native", should I open issue? I have snapdragon 8 gen 1 on sm-x706b and it print(not print Cortex-X2):

$ lscpu --extended=MODELNAME
MODELNAME
Cortex-A510
Cortex-A510
Cortex-A510
Cortex-A510
Cortex-A710
Cortex-A710
Cortex-A710

Looks like it fails to recognize certain CPU part values in /proc/cpuinfo. This can be an issue of lscpu implementation as well.
