This CL removes the remaining visible uses of the "architecture letter" concept. (They are no longer in tool names nor in source directory names.) Because the architecture letter concept is now gone, delete GOCHAR from "go env" output, and change go/build.ArchChar to return an error always. The architecture letter is still used in the compiler and linker sources as a clumsy architecture enumeration, but that use is not visible to Go users and can be cleaned up separately.
