Openscad tests fail on s390x starting with 19.3
Since 19.3.x the majority of tests on the openscad test-suite has been failing to run on s390x, LLVM 9.0.1 was used with 19.2 too where the tests passed.
The tests run some operations on openscad and compare the end result (drawn image) with the expected one, and fail if there are differences. There's no obvious failure output though, so llvmpipe driver seems to think it's doing the right thing.
This could be related to endianness, but s390x is the only platform where I've been able to verify the failure so far.
