Add more variables on NetBSD
Browse files Browse the repository at this point in the history 
Add support for all sysconf variables currently supported by NetBSD's
sysconf.

Keep the SC_* consts in the same order as NetBSD's <unistd.h> [1] and their
implementation in the same order as sysconf() [2].

[1] https://github.com/NetBSD/src/blob/trunk/sys/sys/unistd.h
[2] https://github.com/NetBSD/src/blob/trunk/lib/libc/gen/sysconf.c

Generated and tested on NetBSD 9.2
