Fails to build on s390x

[cpaelzer]

Environment

• DART version: [e.g., master, 6.9.2]
• OS Ubuntu 20.04 + 20.10 (Also Debian)
• Compiler name and version number: GCC-9 + GCC-10

Expected Behavior

Build and tests work fine

Current Behavior

On s390x the build time tests fail

	 17 - test_ForwardKinematics (SEGFAULT)
	 47 - test_SdfParser (SEGFAULT)
	 50 - test_DartLoader (SEGFAULT)
	 51 - test_IkFast (SEGFAULT)

Here the initial build log

I have rebuilt the same with verbosity as recommended - the build is in this PPA and you can access the logs for s390x from there.

Steps to Reproduce

1. Get dart sources and install build dependencies
2. build on s390x
3. run tests

Note - s390x seems to have never built AFAICS
