OK, I managed to compile amd64 successfully, they are here:

https://people.debian.org/~infinity0/apt/pool/contrib/r/rustc/

However I get failures compiling for i386 (i686):

$ sudo cowbuilder --build rustc_1.7.0~~nightly.20160105+dfsg1-1.dsc --basepath /home/pbuilder/base-sid-i386.cow --binary-arch

Normally this should be -Werror=format-security. Digging around a bit gets me this:

mk/rt.mk
# This also removes the -Werror flag specifically to prevent errors during
# configuration.

Not sure the best way to solve it:

1. Remove this functionality that removes -Werror
2. Fix this functionality to remove -Werror(?:=\S*)? instead.

Thoughts?
