I forgot to answer the main question. libkern shouldn't be changed since:
(1) strcpy is so rarely used in the kernel that its speed isn't important.
That's why libkern/strcpy.c is a copy of the generic strcpy.c and not
the i386 strcpy.S.
(2) gcc inlines strcpy() (unless you compile with -O0 or -fno-buitin), so
the libkern version is almost never used.
