Update.
* sysdeps/unix/opendir.c: If O_DIRECTORY_WORKS is defined don't use the hack with tryopen_o_directory to determine at runtime whether it works. * sysdeps/unix/sysv/linux/opendir.c: New file. * sysdeps/unix/sysv/linux/kernel-features.h: Define __ASSUME_O_DIRECTORY if kernel knows O_DIRECTORY.
