x86/boot: #undef memcpy() et al in string.c
undef memcpy() and friends in boot/string.c so that the functions defined here will have the correct names, otherwise we end up up trying to redefine __builtin_memcpy() etc. Surprisingly, GCC allows this (and, helpfully, discards the __builtin_ prefix from the function name when compiling it), but clang does not. Adding these #undef's appears to preserve what I assume was the original intent of the code.
