armel-cross-toolchain-base + gcc-4.[456]-armel-cross were made (by me) 
as a way to get automated builds of cross compiler with use of buildd 
machines. Once we will get cross-arch build dependencies I will convert 
them to binutils-<triplet> + gcc-4.x-<triplet> which will use 
binutils-source, gcc-4.x-source and libc6-dev:<target-arch> as build 
dependencies.

This would be proper way. binutils-<triplet> is easy to do (basically 
armel-cross-toolchain-base limited to $(stamp)/final-binutils step), 
gcc-<triplet> already exists in Ubuntu as gcc-4.[456]-armel-cross package.
