When autoconf was updated from 2.72 to 2.73, we observed a change in the checksum:

The autoconf-generated pyconfig.h file is part of the checksum input:
https://github.com/python/cpython/blob/v3.15.0a8/Tools/jit/_targets.py#L75
Generally, the reason for this checksum is to prevent outdated JIT stencils
when Python is re-configured with different options
(or when the stencils generation code is updated).
As suspected, the change in checksum was caused by a change in pyconfig.h:
--- pyconfig.h
+++ pyconfig.h

+#ifndef _COSMO_SOURCE
+# define _COSMO_SOURCE 1

This is expected, see https://cgit.git.savannah.gnu.org/cgit/autoconf.git/tree/NEWS?h=v2.73#n99
tl;dr when a new autoconf version changes the output of pyconfig.h, the checksum changes as well.
We cannot update the pre-built stencils with the new checksum
because that would make the build fail with older autoconf.
Instead, we ignore the checksum in this check. We care for the contents, not checksums.
