It is asymmetry that we have a minimum supported version of a
toolchain, but no maximum supported version of a toolchain for a given
branch.  I think that's a good thing; imagine if you were stuck on an
old compiler for a stable branch.  No thanks.  I guess we just like to
live dangerously? :P

Also, GKH has voiced support for newer toolchains for older kernel
releases before.  Related to this issue, in fact.
