Maxima in sage is built against ecl

[Julien Puydt <julien.puydt@laposte.net>]

Package: maxima
Version: 5.29.1-1

The maxima used in sage is built with ecl, while the sage in debian 
isn't. That will of course be a problem to package sage ; a very simple 
fix would be to just compile maxima with ecl in debian.

But of course, simple doesn't mean correct : I saw #661803 where someone 
asks for an sbcl-built maxima, so the situation is going to be a pain if 
each and everyone wants maxima built against some variant of common lisp...

I don't know how to handle the situation gracefully, so I open this bug 
CCing debian-science to discuss the matter.

Thanks,
