We need to provide a struct passwd that is compatible with the target system and this is not the case when cross-building from macOS/Linux. It should also be a problem when bootstrapping for an i386 target from a FreeBSD amd64 host since time_t does not match across those systems. However, pwd_mkdb always truncates integer values to 32-bit so this difference does not result in different databases. Reviewed By: brooks Differential Revision: https://reviews.freebsd.org/D25931
