[Patch] Add the ENOSYS description for syslog(2)

[Patch] Add the ENOSYS description for syslog(2)

[WANG Cong]

Hi, Michael!

syslog(2) just returns ENOSYS when CONFIG_PRINTK is not enabled.
This should be described in man pages, I think.

Patch is below.

Thanks.

Thanks!  I've rewritten the text a bit, and applied this change for
