From 57b6fb7eb1f8fc4e80418006db0611e4c365623b Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Tue, 26 Nov 2024 20:12:14 +0100 Subject: [PATCH] Makefile: avoid non-standard sed expressions The '?' that is used in the sed expression that determines MK_ARCH is part of the extended regular expression syntax, but the default behaviour of sed as specified by POSIX is to use only basic regular expression syntax. Use the equivalent '\{0,1\}' instead as suggested by the OpenBSD re_format(7) man page.
