FWIW, there was pretty conclusive evidence produced at the time that the 
vast majority of Linux users were running linux32, and I doubt that's 
changed:

Just because someone doesn't get their builds from us, it doesn't mean 
that they aren't important. I think it would look pretty bad on us if we 
released a version of Firefox which was broken on linux32 as a result of 
this change, though I'm not sure how likely that is. Perhaps the linux64 
tests + whatever QA we get from the community is enough to catch those 
kinds of issues.
