We generally don't edit this file ourselves because it mostly came from CPython.
But I understand this is necessary to correctly support the architecture.
Not to lose the changes when we update this file to new version,
Adding a comment is useful.

Suggested change
if re.match('(aarch64|arm|loongarch64|mips|ppc|powerpc|s390|sparc)', machine):
# XXX: RUSTPYTHON; loongarch64 is locally added in github #4914
if re.match('(aarch64|arm|loongarch64|mips|ppc|powerpc|s390|sparc)', machine):

And also, I found the related CPython patch doesn't include this change. Is it necessary in RustPython?
