Define _DIRENT_MATCHES_DIRENT64 regardless
This patch defines _DIRENT_MATCHES_DIRENT64 to either 0 or 1 and adjust its usage from checking its definition to its value. Checked on a build for major Linux abis. * bits/dirent.h (__INO_T_MATCHES_INO64_T): Define regardless whether __INO_T_MATCHES_INO64_T is defined. * sysdeps/unix/sysv/linux/bits/dirent.h: Likewise. * dirent/alphasort.c: Check _DIRENT_MATCHES_DIRENT64 value instead of definition. * dirent/alphasort64.c: Likewise. * dirent/scandir.c: Likewise. * dirent/scandir64-tail.c: Likewise. * dirent/scandir64.c: Likewise. * dirent/scandirat.c: Likewise. * dirent/scandirat64.c: Likewise. * dirent/versionsort.c: Likewise. * dirent/versionsort64.c: Likewise. * include/dirent.h: Likewise.
