Looks like only #799036 (against build-dependency openspecfun) is 
stalling.

To repeat myself from IRC, I suggest to ask at #emdebian for help 
convincing openspecfun maintainer - I believe the common approach is to 
rely on buildd's to automagically skip packages failing due to porting 
issues, but really the Emdebian guys (e.g. Wookie) knows better than me.

Your choice, but seems to me you need not wait to push the openspecfun 
issue further: Perhaps you mean you've made your point and it wasn't 
heard, and the new Julia release is an excuse to try convince adding 
_specific_ known succesful archs - but IMO that sidesteps the issue of 
thinking that each package needs to micro-manage arch support, and I 
dearly recommend you to instead try get others to support your original 
point instead.

Cool!

If you've done it on an up-to-date pristine Debian Sid system, then it 
would be good that you file a bugreport against gcc about that!

Nice :-)
