So far I've been able to confirm everything you said: PostGIS won't compile 
with CGAL 4.12 and SFCGAL. David and I were coordinating on upgrading CGAL 
from 4.9 and the 4.11 upgrade was fine but I missed how it broke PostGIS with 
the more recent 4.12. I suppose it's because it's only an optional dependency 
for PostGIS ...

There are a few ways of fixing the issue: remove SFCAL; add --without-sfcgal 
to PostGIS's configure; or downgrade CGAL to 4.11. The choice likely depends 
on whether you need the additional PostGIS functions provided by SFCAL and 
whether you need SFCGAL on your system for something else!
