mktime: fix unlikely race+overflow bug
Problem reported by Alexandre Oliva in:
https://sourceware.org/bugzilla/show_bug.cgi?id=16346
* lib/mktime.c (__mktime_internal): Access *OFFSET only once,
to avoid an unlikely race if the compiler delays a load and
if this cascades into a signed integer overflow.
