Don't use gcc's __builtin_*() functions #if defined(_STANDALONE) 

because they could be larger than __OPTIMIZE_SIZE__'ed libsa ones and
__builtin_memcpy() on vax rejects NULL (i.e. copying from/to address 0x0).

No particular comments on tech-toolchain.

Tested on alpha, arc, cobalt, hp300, i386, landisk, macppc, news68k, sgimips,
sparc, sparc64, sun3, and vax (on simh).
