linux: Consolidate Linux splice syscall
This patch consolidates the splice Linux syscall generation on
sysdeps/unix/sysv/linux/splice.c. It basically removes it from
architectures auto-generation list.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu,
sparc64-linux-gnu, and sparcv9-linux-gnu.
* sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Add splice.
(CFLAGS-splice.c): New flag.
* sysdeps/unix/sysv/linux/splice.c: New file.
* sysdeps/unix/sysv/linux/syscalls.list (splice): Remove from
auto-generation syscall list.
* misc/Makefile (CFLAGS-splice.c): New rule.
