s390x is failing new tests scal.c

[mattip]

I am building OpenBLAS on s390x on travis inside a quay.io/pypa/manylinux2014_s390x docker (which uses gcc 10.4) via

CFLAGS="-fvisibility=protected -Wno-uninitialized" \
make BUFFERSIZE=20 DYNAMIC_ARCH=1 USE_OPENMP=0 NUM_THREADS=64 \
    BINARY=64 INTERFACE64=1 SYMBOLSUFFIX=64_ LIBNAMESUFFIX=64_ \
    OBJCONV=$PWD/objconv/objconv

using commit d11e734 and am seeing some

Note I am not specifying TARGET on s390x since I have no idea what is an acceptable "minimum".

This is not a deal breaker for NumPy/SciPy since we do not release wheels for that platform, but I thought I would report it anyway.

somewhat expected but I had had problems accessing our Jenkins CI for a while (one needs to be logged in there to see the logs).
"acceptable minimum" for dynamic_arch on zarch would be the zarch_generic target I guess, but I have no idea if there is anything of practical importance left below the Z13

Closing as fixed (verified by #4843)

Thanks!
