+Subject: [PATCH] libbb: mark scripted_main() as externally visible
+
+Building with individual binaries enabled fails when embedded
+script applets are included:
+
+   /tmp/ccIvMFZg.o: In function `main':
+   applet.c:(.text.main+0x20): undefined reference to `scripted_main'
+
+Mark scripted_main() as externally visible.
