[Pkg-rust-maintainers] Alpha2 upload [was: build profiles]

[Angus Lees]

Oh, I see it wasn't at all understood - sorry, I thought when the build
profiles stuff was merged onto master that it was moving ahead with the
understanding and agreement of the rest of pkg-rust-maintainers :(

I wrote the README.source text in a sort of future tense, assuming the
reader was reading it at a time when rust-1.0 was released, and rustc was
in the Debian archive - you can see things like "apt-get source rustc".  I
was assuming that the uploader had a better idea of the where we were in
the rapidly evolving process up to that point, but that obviously failed as
soon as the uploader wasn't me :/

Yes, revert it to whatever state you're comfortable with, and we can always
reattempt the build-profile approach _after_ rustc can build itself :/
