Failing CI builds

[junghans]

• opensuse:latest lammps seems to time out (workaround in opensuse: remove lammps again buildenv#198)
• ubuntu:devel that is libint2 warning on ubuntu:devel #1080 again, see suggestion in there
• fedora:intel with icc, runs out of space for debug build, no idea right now, but icc is dead (``icpc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is deprecated and will be removed from product release in the second half of 2023.`) so maybe not worth investigating!

[junghans]

opensuse:latest is working again.

[baumeier]

I was not even aware that we were still using icc in parts of the CI. I think we can just drop this run, since we do have the intel-oneapi run using icpx, no?

[junghans]

We build with both icpc and icpx, so let's drop it!

[junghans]

I will try to make a draft PR later today for you to review.

Now on fedora:rawhide:

writing output... [  0%] Architecture
Theme error:
An error happened in rendering the page Architecture.
Reason: UndefinedError("'style' is undefined")
ninja: build stopped: subcommand failed.

[baumeier]

Sphinx version was v5.3.0 in fedora::latest but jumped to v7.1.2 in fedora::rawhide. Seems there was/is an incompatibility with readthedocs, see readthedocs/sphinx_rtd_theme#1464

[junghans]

@baumeier the gcc fails with mkl.

gmake[2]: *** [xtp/src/tests/CMakeFiles/unit_test_segmentmapper.dir/build.make:79: xtp/src/tests/CMakeFiles/unit_test_segmentmapper.dir/test_segmentmapper.cc.o] Error 1

no good idea why yet....
