Yes, I did the following at the top-level of base
git pull
git checkout R7.0.7
git submodule update

git status shows no modified files in configure/os.  Then I did:

make realclean
make realuninstall
make -sj

Is this a clean (re)build?  (fresh clone or "make distclean")

The automatic detection logic should emit a "?=" assignment.

So other forms of definition "=" or from the command line should take precedence.

You should not have to make any change to configure/ files.
