+From f839de283c44ffe46a2d14bfdf854c145abd8ed6 Mon Sep 17 00:00:00 2001
+From: Colin Ian King <colin.king@canonical.com>
+Date: Mon, 19 Jul 2021 20:49:34 +0100
+Subject: [PATCH] Detemine minimal stack size via sysconf, then
+ PTHREAD_STACK_MIN then guess
+
+Don't rely on PTHREAD_STACK_MIN being defined, use sysconf, then
+PTHREAD_STACK_MIN if it is defined, then 8K default.
