[Bug middle-end/34477] [4.3 regression] Standard autoconf mktime test is too slow when compiled with -O2

Timings with gcc 3.4.6 :

[~]> gcc -o mktime mktime.c
[~]> time ./mktime

real    0m0.052s
user    0m0.021s

[~]> gcc -O2 -o mktime mktime.c
[~]> time ./mktime

real    0m0.032s
user    0m0.021s
sys     0m0.011s

So this is a regression.
