Merge #1177

1177: Add CLK_TCK to SysconfVar r=asomers a=cjbassi http://man7.org/linux/man-pages/man3/sysconf.3.html says that the corresponding variable is obsolete, but I think that just means the constant defined in limits.h is obsolete. Checking the value using sysconf is still valid. Co-authored-by: Caleb Bassi <[email protected]>
