arch/tile: make glibc's sysconf(_SC_NPROCESSORS_CONF) work correctly
glibc assumes that it can count /sys/devices/system/cpu/cpu* to get the number of configured cpus. For this to be valid on tile, we need to generate a "cpu" entry for all cpus, including the ones that are not currently allocated for Linux's use. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
