Got this figured out. tested on too many machines - the last version 
built was on AIX5 - which does not have uuid() functions in libc.a.

Running on AIX6 - I get:

(Pdb) py_uuid
<module 'uuid' from '/data/prj/python/git/gcc-python3-3.7/Lib/uuid.py'>
(Pdb) c_uuid
<module 'uuid' from '/data/prj/python/git/gcc-python3-3.7/Lib/uuid.py'>
(Pdb) import _uuid
(Pdb) _uuid
<module '_uuid' from 
'/data/prj/python/git/gcc-python3-3.7/build/lib.aix-6.1-3.7/_uuid.so'>
(Pdb)

However, have a new question - why are py_uuid and c_uuid 'equivalent'. 
(_uuid is shown just to show that it can be imported).

A comment - perhaps a new bpo/issue topic. When trying to run the tests 
from a freshly built version - it still seems to default to looking at 
the installed version first. And that can make debugging very very hard 
(which modules are actually getting loaded?!). In this case, there also 
seem to be a python2 and python3 incompatibility - notice the python2.7 
pdb reference!
