Bug report

Bug description:

Sincede2a73dpython-config.sh.in is using bashisms but declaring#!/bin/sh as the shell. As a result, it now throws errors on systems using non-bash shells:

$ python3.13-config /usr/bin/python3.13-config: 8: [[: not foundUsage: /usr/bin/python3.13-config --prefix|--exec-prefix|--includes|--libs|--cflags|--ldflags|--extension-suffix|--help|--abiflags|--configdir|--embed

FWICS, there's no reason to use[[ ... ]] over plain shell[ ... ] there.
