Hi Kenneth:

I can recreate this issue on Haswell, Skylake-X, and KNL running SLES 12, Clear Linux, and Centos 7.5. I've tried 18.1 and 18.2. It's still present across the board with Intel C/C++ 18.0.2.199. On the Centos 7.5.1804 image, the build will seemingly complete, but since _sha3 didn't actually compile, the regression tests will fail with errors of the form:

$ /dev/shm/testinstall/icc/python/3.6.5/bin/python3 -m test
ERROR:root:code for hash sha3_224 was not found.
Traceback (most recent call last):
  File "/dev/shm/testinstall/icc/python/3.6.5/lib/python3.6/hashlib.py", line 121, in __get_openssl_constructor
    f = getattr(_hashlib, 'openssl_' + name)
AttributeError: module '_hashlib' has no attribute 'openssl_sha3_224'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/dev/shm/testinstall/icc/python/3.6.5/lib/python3.6/hashlib.py", line 243, in <module>

Searching about, it looks like you may have seen something similar in EasyBuild:

https://github.com/easybuilders/easybuild-easyconfigs/pull/5086

but it doesn't look like the root cause was sussed out.
