This patch splits x86_64 out of the main Linux kernel-features.h. Tested x86_64 that there are no changes to disassembly of installed shared libraries. * sysdeps/unix/sysv/linux/x86_64/kernel-features.h: New file. * sysdeps/unix/sysv/linux/kernel-features.h [__x86_64__] (__ASSUME_ACCEPT4_SYSCALL): Do not define. [__LINUX_KERNEL_VERSION >= 0x020621 && __x86_64__] (__ASSUME_RECVMMSG_SYSCALL): Likewise. [__LINUX_KERNEL_VERSION >= 0x030000 && __x86_64__] (__ASSUME_SENDMMSG_SYSCALL): Likewise. [__x86_64__ && __LINUX_KERNEL_VERSION >= 0x030100] (__ASSUME_GETCPU_SYSCALL): Likewise.
