posix: Consolidate Linux fdatasync syscall
This patch consolidates the fdatasync Linux syscall generation on sysdeps/unix/sysv/linux/fdatasync.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. * misc/makefile (CFLAGS-datasync.c): New flag. * nptl/makefile (CFLAGS-datasync.c): Likewise. * sysdeps/unix/sysv/linux/syscalls.list (fdatasync): Remove from auto-generation syscall list. * sysdeps/unix/sysv/linux/fdatasync.c: New file.
