Merge r191883,191966,191973 from HEAD to stable/7:

Linux exports HZ value to user space via AT_CLKTCK auxiliary vector
entry since 2.4.0.
Being exported, AT_CLKTCK is returned by sysconf(_SC_CLK_TCK),
glibc falls back to the hard-coded CLK_TCK value when aux entry
is not present.

Glibc versions prior to 2.2.1 always use hard-coded CLK_TCK value.

For older applications/libc's which depends on hard-coded CLK_TCK
value user should set compat.linux.osrelease less than 2.4.0.

linux_times() shall use the value that is exported to user space.
