I agree they are of no real use to end users but I still keep them in
our ghostscript package because I need them for our quick smoke test
via our separated ghostscript-testing package, see
https://build.opensuse.org/package/show/Printing/ghostscript-testing
plus the testing packages gutenprint-testing and hplip-testing,
for some background information you may have a look at
https://bugzilla.opensuse.org/show_bug.cgi?id=1082896#c5

On older systems I cannot build Ghostscript with SUSE's lcms2
because on SLE11 and on SLE12-SP1 there is liblcms2-2-2.5
which is too old so that configure fails there with
  "configure: error: lcms2 not found, or too old".

But there is no configure option to build it without lcms2
so that for SLE11 and SLE12-SP1 it is built with the lcms2art
in Ghostscript, cf.
https://build.opensuse.org/package/view_file/Printing/ghostscript/ghostscript.changes?expand=1
and for the details how it is actually built see
https://build.opensuse.org/package/view_file/Printing/ghostscript/ghostscript.spec?expand=1

This means openSUSE users who use our newest ghostscript package
from the openSUSE Build Service development project "Printing"
on their SLE11 or SLE12-SP1 systems act now as early testers
of lcms2art which is perfectly o.k. because
https://build.opensuse.org/project/show/Printing
reads (excerpts):
----------------------------------------------------------
The "Printing" development project may contain
new software or work-in-progress changes of
existing software that might neither be in
a stable state nor fit well into currently
installed systems.
...
The packages in the "Printing" project are without
any guarantee or warranty and without any support.
...
If a new version does not work it should usually
help to downgrade (and to reconfigure as needed)
to get it working again.
----------------------------------------------------------

FYI:

Regarding our ppc64le-support.patch that contained
a fix for lcms2art/include/lcms2art.h in Ghostscript:

This is what I had in ppc64le-support.patch

It is the same code change as we had since Ghostscript 9.15

I don't know if that is still needed to make things work
on the ppc64le architecture.
