Well, the patch contains much more changes, which are difficult to check.
I looked at the changes in fbedacfc8 and it looks like corresponding
fix to _shipped files is just:

+       char *env;
        FILE *f;
 
        f = fopen(name, "r");
        if (!f && name[0] != '/') {
                env = getenv(SRCTREE);
                if (env) {
+                       char *fullname = alloca(strlen(env) + strlen(name) + 2);
                        sprintf(fullname, "%s/%s", env, name);
                        f = fopen(fullname, "r");
                }

I applied the above patch to git. Does it work for you now?
