That, and the fact that your "ls" shows no derived files, means that the
Makefile is choosing not to do anything, which a look at the Makefile
says must be because shared_libpython isn't getting set. (As of 9.5
we've changed that to not fail silently, but in 9.3 this is what it does.)

There are two possibilities here: either your python3 installation does
not include a shared-library version of libpython, or it does but the
configure+Make process is failing to detect that. Probably should
establish which of those it is before going further.
