Can you try the following in modprobe.c?

static struct dep_t *build_dep(void) 
{
...
        filename = xasprintf("/lib/modules/%s/modules.dep", un.release);
        fd = open(filename, O_RDONLY);
        if (ENABLE_FEATURE_CLEAN_UP)
                free(filename);
        if (fd < 0) {
                /* Ok, that didn't work.  Fall back to looking in /lib/modules */
                fd = open("/lib/modules/modules.dep", O_RDONLY);
                if (fd < 0) {
-                       bb_error_msg_and_die("cannot parse modules.dep");
+                       bb_error_msg("cannot parse modules.dep");
+                       return NULL;
                }
        }
...
