The 2 lines are subtly different - the new one is plural.

According to the apt docs some systems, like x64, can support several
binary types i.e. i386 or x64.  In these cases the the Architures
(plural) entry is used to specify alternatives.  I'm guessing, but I
suspect that without this entry your x64 system was looking for i386
alternatives.

Good news.  Maybe just a coincidence, but just in case I'll amend
mythbuild.sh.

Thanks for the feedback.
