This patch consolidates the open_by_handle_at Linux syscall generation on sysdeps/unix/sysv/linux/open_by_handle_at.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 (sysdep_routines): Add open_by_handle_at. (CFLAGS-open_by_handle_at.c): New flag. * sysdeps/unix/sysv/linux/open_by_handle_at.c: New file. * sysdeps/unix/sysv/linux/syscalls.list (open_by_handle_at): New file. * misc/Makefile (CFLAGS-open_by_handle_at.c): New rule.
