With a unified x86 architecture, the decision to compile with 32 or 64-bit mode isn't really different from SMP vs UP, PAE vs non-PAE and so on. It's just a config option with global effects. Over time, the number of config options with are really 32 or 64-bit specific will probably pretty small.

The architecture is now x86, with a further 32 or 64-bit parameter. We already have config options for setting the sub-architecture.
