I tried to merge your work into our.
However, I cannot get the package to build using the build profile
(documented in README.Debian)

This fails:
$ apt-get source --compile --build-profiles=dlstage0,nodocs rustc
Reading package lists... Done
Building dependency tree      
Reading state information... Done
E: Unable to find a source package for rustc

(btw, your doc has a typo, it is build-profiles, not build-profile).

Cheers,
