A couple of timestamp tests are failing on mips64el. Please let me know
if you need more info.
What happens if you run the following shell commands, using the
just-built gzip? What gzip.tr file is generated?
TZ=UTC0
export TZ
rm -f in in.gz
touch -t 190101010000 in
strace -v -o gzip.tr ./gzip in
The key part will be what is in the last few lines of gzip.tr when gzip
looks at the file "in". Here's how gzip.tr ends on my Ubuntu 20.10 ext4
system:

Perhaps the timestamps are somehow messed up on your platform, in which
case you need to investigate why fstat is returning incorrect timestamps
for the input file.
