+Subject: [PATCH] gen_build_files: Use C locale when calling sed on globbed files
+
+sort order is different based on chosen locale and also default shell
+being bash or dash
+
+This sets the environment variable LC_ALL to the value C, which will
+enforce bytewise sorting, irrespective of the shell
+
+Upstream-Status: Pending
