BSS memory pages allocating also demand. You not have gain memory, and
lose disk space.

My idea for all gain space:

#define _BB_DIR_BIN  "\000"
#define _BB_DIR_SBIN "\001"
.....

const struct BB_applet applets[] = {
-#define APPLET(a,b,c,d) {a,b,c,d},
+#define APPLET(a,b,c,d) {c a, b, d},

#define APPLET_NAME(pointer_to_BB_applet) \
                        &(pointer_to_BB_applet->name[1])
