From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] setup: refresh config.guess/config.sub for riscv64

Upstream-Status: Inappropriate [riscv64 build infra, irrelevant to jeffdaily/parasail-python]

build_parasail() downloads a plain GitHub archive snapshot of
jeffdaily/parasail's master branch (not a `make dist` release tarball),
so it carries no generated `configure` and falls back to `autoreconf
-fi`. That only installs *missing* auxiliary files; it does not
overwrite the config.guess/config.sub already committed to the C
library's tree, and those predate riscv64 (added to config.sub in
2017), so `./configure` dies with "cannot guess build type; you must
specify one" on the riscv64 manylinux runner -- the exact shape of
CLAUDE.md gotcha 138 (libspatialite's 2009-dated pair hitting the same
wall on aarch64/riscv64).

The manylinux_riscv64 image already carries a current automake, whose
own config.guess/config.sub do recognise riscv64 (gotcha 138's fix), so
copy those over the stale ones before configure runs.
