What I really think you need to do is do a full build without CFLAGS or 
CXXFLAGS set.  Then compare with a build with those settings.

My test logs are not complete, but if you really want me to, I can do a 
full build as of 20200721 with all tests.  I can upload the test files 
to anduin for you to compare.
