[PATCH 2/6] Split i386 out of main Linux kernel-features.h.
This patch splits i386 out of the main Linux kernel-features.h. Tested x86 that there are no changes to disassembly of installed shared libraries. * sysdeps/unix/sysv/linux/i386/kernel-features.h: New file. * sysdeps/unix/sysv/linux/kernel-features.h [__i386__] (__ASSUME_SOCKETCALL): Do not define. [__LINUX_KERNEL_VERSION >= 0x020621 && __i386__] (__ASSUME_RECVMMSG_SYSCALL): Likewise. [__i386__] (__ASSUME_RECVMMSG_SYSCALL_WITH_SOCKETCALL): Likewise. [__LINUX_KERNEL_VERSION >= 0x030000 && __i386__] (__ASSUME_SENDMMSG_SYSCALL): Likewise. [__i386__] (__ASSUME_SENDMMSG_SYSCALL_WITH_SOCKETCALL): Likewise.
