parasail wraps the parasail SIMD C library via ctypes, bundling a platform-specific libparasail.so inside an otherwise "none"-ABI wheel. PyPI 1.3.4 ships manylinux_x86_64/musllinux_i686/macOS/Windows wheels but no riscv64, and jeffdaily/parasail's configure.ac probes each SIMD ISA independently with no architecture allow-list, so it already degrades gracefully to a scalar build on an unrecognised host. Mirrors upstream's own wheels.yml (plain cibuildwheel, single cp310 - now cp312 - build since bdist_wheel.finalize_options() forces every wheel to the same py2.py3-none tag regardless of interpreter). Patches setup.py to refresh config.guess/config.sub from the manylinux image's own automake before the C library's autoreconf runs, since the upstream C library's committed pair predates riscv64 (gotcha 138).
