Hmmm, this will change with Thomas' patch series. Instead of the enums
we'd have references to the programmer structs. Maybe we'd have to
enable linker garbage collection*, but then a C `if` should do.

(*) I wouldn't want such advanced linker features for the flashrom
program yet but for tests I see no reason to avoid it.
