posix: Consolidate Linux fsync syscall
This patch consolidates the fsync Linux syscall generation on sysdeps/unix/sysv/linux/fsync.c. It basically removes it from architectures auto-generation list. For arm it also removes the __errno_location call since fsync is not called with SYSCALL_CANCEL with call arch-specific INLINE_SYSCALL macro which in turn will call __set_errno macro (and setting errno directly). 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-fsync.c): New flag. * nptl/Makefile (CFLAGS-fsync.c): Likewise. * sysdeps/unix/syscalls.list (fsync): Remove from auto-generation syscall list. * sysdeps/unix/sysv/linux/fsync.c: New file. * sysdeps/unix/sysv/linux/arm/localplt.data [libpthread.so] (__errno_location): Remove.
