With some digging, we found the real problem:
mips64 has y2106 problem
the struct stat in asm/stat.h, the timestamp is unsigned int (uint32_t),
so in the SYS_stat, -1 is converted to 0xffffff.
Then in glibc wrapper of stat, 0xffffffff need to convert to int64_t,
then, it is converted to 2016.
So, current, for gzip, we can just ignore the test fails on mips64el.
To solve this problem: I guess that we can wrap `statx' instead of
`stat' in glibc.
Since the timestamp in bits/stat.h is 64bit, there will no ABI broken.
