Subject[PATCH v5 01/12] vsprintf: factorize "(null)" string
Date
Change "<NULL>" to "(null)", unifying 3 equal strings.
glibc also uses "(null)" for the same purpose.

It decreases code size by 7 bytes:
text data bss dec hex filename
15765 0 8 15773 3d9d vsprintf.o (ex lib/lib.a-BEFORE)
15758 0 8 15766 3d96 vsprintf.o (ex lib/lib.a-AFTER)
