What a bug.

Laurent, perhaps a good candidate for 4.2?

Yes, in Alpine qemu+binfmt_misc+chroot environment, this bug caused
all files to have an observed mtime set to the UNIX epoch, which
caused problems with building Autoconf-based applications.  This
really irked me so I took the time to dig into it.
