linux: Consolidate Linux tee implementation
This patch consolidates the tee Linux syscall generation on
sysdeps/unix/sysv/linux/tee.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 (sysdeps_routines): Add tee.
(CFLAGS-tee.c): New rule.
* sysdeps/unix/sysv/linux/syscalls.list: Remove tee from
auto-generated list.
* sysdeps/unix/sysv/linux/tee.c: New file.
