x86/boot: #undef memcpy() et al in string.c
commit 18d5e6c34a8eda438d5ad8b3b15f42dab01bf05d upstream.
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.
