I think we need to coordinate this when we change the kernel to
add truncation of the 64-bit time values. It sounds like glibc
does an 'unsigned int' to 'long long' conversion for the legacy
stat syscall, rather than a conversion from a signed value, and
it would be helpful to have a matching interpretation between
kernel and glibc.

What is the glibc behavior for i386 with 64-bit time_t on a
kernel without statx? Does that also intepret a time value
of -1u as a 2106 timestamp, or does it convert that into a
1969 timestamp like the other (not mips/pa-risc) 64-bit
architectures do?
