The buildbot started experiencing some failures. First after https://github.com/python/cpython/commit/ddbef71a2c166a5d5dd168e26493973053a953d6 this test started failing with:

======================================================================
ERROR: test_disallow_instantiation (test.test_hashlib.HashLibTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/buildbot/buildarea/3.x.cstratak-RHEL8-fips-x86_64.no-builtin-hashes-except-blake2/build/Lib/hashlib.py", line 160, in __hash_new
    return _hashlib.new(name, data, **kwargs)
ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for FIPS
During handling of the above exception, another exception occurred:

    raise ValueError('unsupported hash type ' + name)
ValueError: unsupported hash type md5


And then after https://github.com/python/cpython/commit/91554e4c5ca3c762998296522f854a7166ba84f0 there is another failure:

======================================================================
