akpm@linux-foundation.org 00699e8472 uml: fix WARNING: vmlinux: 'memcpy' exported twice
Fix the following warning on x86_64:

LD vmlinux.o
MODPOST vmlinux.o
WARNING: vmlinux: 'memcpy' exported twice. Previous export was in vmlinux

For x86_64, this symbol is already exported from arch/um/sys-x86_64/ksyms.c.
