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 new macro that works for both hurd and linux to detect when
setitimer and getitimer support 64-bit time_t.
Fixes commit 6e8a0aac2f ("time: Fix overflow itimer tests on 32-bit
systems").

Hi Joseph,
I know you mentioned defining a new macro, I was not sure if you meant in the
test or globally. I opted to add this to the test as I don't see a good reason
to add the macro to hurd which is only needed for this test.
I build tested this on i686-gnu and ran my tests on or1k and it does work.

As suggested by Adhemerval I will create a v2 of this patch moving the gist of
this into support/xtime.h.
