python-cpuinfo is missing code to detect Alpha CPUs.  The attached
patch adds such code.

Could you apply the patch soon as dependent packages fail to build
from source without it, for example, pytables, see:
https://buildd.debian.org/status/fetch.php?pkg=pytables&arch=alpha&ver=3.11.0-2&stamp=1772245356&raw=0

Example failure:

ERROR: test00_description (tables.tests.test_tables.CompressBlosc2TablesTestCase.test00_description)
