Consolidate scandir{at}{64} implementation
This patch consolidates scandir{at}{64} implementation on just the default dirent/scandir{at}{64}{_r}.c ones. It changes the logic to follow the conventions used on other code consolidation: * scandir{at} is only built for _DIRENT_MATCHES_DIRENT64 being 0. * scandir{at}{64} is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. Also on Linux the compat symbol for old non-LFS dirent64 definition requires a platform-specific scandir64.c. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and powerpc64le-linux-gnu. * dirent/scandir-tail-common.c: New file. * dirent/scandir-tail.c: Use scandir-tail-common.c. (__scandir_tail): Build iff _DIRENT_MATCHES_DIRENT64 is not defined. * dirent/scandir.c: Use scandir-tail-common.c. * dirent/scandirat.c: Likewise. * dirent/scandir64-tail.c: Use scandir-tail-common.c. * dirent/scandir64.c (scandir64): Always build and alias to scandir if _DIRENT_MATCHES_DIRENT64 is defined. * dirent/scandirat64.c (scandirat64): Likewise. * include/dirent.h (__scandir_tail): Only define iff _DIRENT_MATCHES_DIRENT64 is not defined. (__scandir64_tail): Define regardless. (__scandirat, scandirat64): Remove libc_hidden_proto. * sysdeps/unix/sysv/linux/arm/scandir64.c: Remove file. * sysdeps/unix/sysv/linux/m68k/scandir64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/scandir64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/scandir64.c: Likewise. * sysdeps/unix/sysv/linux/i386/scandir64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/scandir64.c: Likewise. * sysdeps/unix/sysv/linux/scandir64.c: New file.
