https://github.com/osandov/drgn/pull/427 From 4aad3f174ceaaa740728ba92181d9d156f70abac Mon Sep 17 00:00:00 2001 From: Sam James Date: Tue, 27 Aug 2024 21:03:42 +0100 Subject: [PATCH] libdrgn: fix bashism in M4 macro configure scripts need to be runnable with a POSIX-compliant /bin/sh. On many (but not all!) systems, /bin/sh is provided by Bash, so errors like this aren't spotted. Notably Debian defaults to /bin/sh provided by dash which doesn't tolerate such bashisms as '=='. This retains compatibility with bash.
