Even more important, all architectures should get all their 
required patches into upstream binutils and gcc.

There might be some time at the beginning of a port until this state is 
reached, but for the majority of our architectures plain upstream
binutils 2.18.50.0.5 and gcc 4.3.0 already give a successful kernel 
build.

And I'm regularly poking arch maintainers to get their binutils and gcc 
patches upstream.

Regarding "required toolchain versions" - I'm not even sure anyone 
really knows what the minimum binutils version for x86 is...
