[Bug libc/1176] New: sys_times return value

["navlrac at hotmail dot com" <sourceware-bugzilla at sources dot redhat dot com>]

Quoting Russell King's explaination of original bug I filed.

ARM folk have recently pointed out a problem with sys_times().
When the kernel (2.6) boots, we set jiffies to -5 minutes. This causes
sys_times() to return a negative number, which increments through
zero.

However, some negative numbers are used to return error codes.
Hence, there's a period of time when sys_times() returns values
which are indistinguishable from error codes shortly after boot.

This probably only affects 32-bit architectures. However, one
wonders whether sys_times() needs force_successful_syscall_return().

Also, it appears that glibc does indeed interpret the return value
from sys_times in the way I describe above on at least ARM and x86.
Other architectures may be similarly affected.
