It means that it is not supported. From SUS2
(http://www.unix-systems.org/onlinepubs/007908799/xsh/sysconf.html):
RETURN VALUE
If name is an invalid value, sysconf() returns -1 and sets errno to
indicate the error. If the variable corresponding to name is
associated with functionality that is not supported by the system,
sysconf() returns -1 without changing the value of errno.
