libc 2.31/i686: operation not permitted for preserving timestamps

[Elan Ruusamäe]

i've got reports that cp -a (or just cp --preserve=timestamps) fails on 
i686 and glibc 2.31


from strace i've grabbed such error:


        utimensat_time64(4, NULL, [{tv_sec=1584393052, tv_nsec=0} /* 
2020-03-16T23:10:52+0200 */, {tv_sec=1584393052, tv_nsec=0} /* 
2020-03-16T23:10:52+0200 */], 0) = -1 EPERM (Operation not permitted)


i believe it's related to large inode on fd=4 and glibc just reports it 
incorrectly
