Dear all,
I just managed (using tricks to avoid a few remaining issues in
cythonization and packages) to get make succeed in building sage with
SAGE_PYTHON3=yes
Sadly, but not unexpectedly, sage then crashes at startup. Apparently, it
cannot not find/import any cython extension..

Here is a snapshot of the end of compilation and tentative run:
real 61m21.708s

Sage build/upgrade complete!

Forcing sage-location, probably because a new package was installed.
Updating various hardcoded paths...
(Please wait at most a few minutes.)
DO NOT INTERRUPT THIS.
Done updating paths.
