This is due to the MD th_x86_pvc_last_systime being 64bit. Change amd64 VDSO_TIMEHANDS_MD32 to not use uint64_t, replace it with pair of uint32_t, as it is done for all other members.

This happens when building the program as 32bit executable on 64bit FreeBSD and
run the executable on 64bit FreeBSD.
