time: Fix compile error in itimer test affecting hurd
The recent change to use __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64 to avoid doing 64-bit checks on some platforms broke the test for hurd where __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64 is not defined. With error: tst-itimer.c: In function 'do_test': tst-itimer.c:103:11: error: '__KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64' undeclared (first use in this function) 103 | if (__KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ tst-itimer.c:103:11: note: each undeclared identifier is reported only once for each function it appears in Define a support helper to detect when setitimer and getitimer support 64-bit time_t. Fixes commit 6e8a0aac2f ("time: Fix overflow itimer tests on 32-bit systems"). Cc: Adhemerval Zanella <adhemerval.zanella@linaro.org> Cc: Joseph Myers <joseph@codesourcery.com>
