Yes. If you cd into that directory and do `sha1sum * | cut -f 1 -d ' '
| sort -u`, you'll see that there are only two different files. On my
machine, after I extract the data.tar.xz inside the deb downloaded
from packages.debian.org, I see the following:
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 kgsl_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 kms_swrast_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 msm_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 nouveau_dri.so
-rw-r--r--  3 ruslan users 2952208 2017-03-21 16:02 nouveau_vieux_dri.so
-rw-r--r--  3 ruslan users 2952208 2017-03-21 16:02 r200_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 r300_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 r600_dri.so
-rw-r--r--  3 ruslan users 2952208 2017-03-21 16:02 radeon_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 radeonsi_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 swrast_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 vc4_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 virtio_gpu_dri.so
-rw-r--r-- 11 ruslan users 6875452 2017-03-21 16:02 vmwgfx_dri.so

Notice the 11 hard links to one set of files and 3 to the other. Thus
`du -sch .` executed inside this directory only gives me only 9.4 MiB,
unlike your list, which would give about 99.4 MiB because each file is
copied anew.

Also note that the Jessie package is also not that small if you copy
the files instead of hard-linking. I suspect it may be really a bug
introduced in Debian Stretch — either somewhere in dpkg or maybe in
tar if your list is the result after dpkg/apt-get install.

You can check if the bug is in tar or not: try extracting data.tar.xz
inside the deb manually (i.e. using `tar xf data.tar.xz`) and get
refcounts of 1, then it must be a new bug in tar. For reference, my
GNU tar 1.26 works correctly.
