linux: Consolidate Linux vmsplice syscall
This patch consolidates the vmsplice Linux syscall generation on sysdeps/unix/sysv/linux/vmsplice.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 (CFLAGS-vmsplice.c): New flag. * sysdeps/unix/sysv/linux/syscalls.list (vmsplice): Remove from auto-generation syscall list. * sysdeps/unix/sysv/linux/vmsplice.c: New file. * misc/Makefile (CFLAGS-vmsplice.c): New rule.
