While building a custom kernel for the VAX, I came across undefined
references to memcpy and memset, from bf_skey.o and sha2.o.

Looking through definitions for memcpy I found various things that might
be relevant. Apparently none of these kick in.

lib/libkern/bcopy.c:66

/*
 * Copy a block of memory, handling overlap.
 * This is the routine that actually implements
 * (the portable versions of) bcopy, memcpy, and memmove.
 */
#ifdef MEMCOPY
void *
memcpy(dst0, src0, length)
#else
#ifdef MEMMOVE
void *
memmove(dst0, src0, length)
#else
void
bcopy(src0, dst0, length)
#endif
#endif
        void *dst0;
        const void *src0;
        size_t length;
{


lib/libkern/libkern.h:233 (VAX uses gcc version 2.95.3 20010315 (release)
(NetBSD nb4))

/* Prototypes for which GCC built-ins exist. */
void    *memcpy __P((void *, const void *, size_t));
int      memcmp __P((const void *, const void *, size_t));
void    *memset __P((void *, int, size_t));
#if __GNUC_PREREQ__(2, 95) && !defined(__vax__)
#define memcpy(d, s, l)         __builtin_memcpy(d, s, l)
#define memcmp(a, b, l)         __builtin_memcmp(a, b, l)
#define memset(d, v, l)         __builtin_memset(d, v, l)
#endif

lib/libsa/memcpy.c:41

void *
memcpy(s1, s2, n)
        void *s1;
        const void *s2;
        size_t n;
{


arch/vax/include/macros.h:77

static __inline__ void * __attribute__((__unused__))
memcpy(void *to, const void *from, size_t len)
{
