posix: Consolidate Linux nanosleep syscall
This patch consolidates the nanosleep Linux syscall generation on sysdeps/unix/sysv/linux/nanosleep.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. * nptl/Makefile (CFLAGS-nanosleep.c): New rule. * posix/Makefile (CFLAGS-nanosleep.c): Likewise. * sysdeps/unix/sysv/linux/nanosleep.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Remove nanosleep from auto-generated list.
