Why would we want both variants?
I think we should stay away from this kind of compile-time configuration
options as much as possible. In my opinion, the CONFIG_XXX stuff as found in
the Linux kernel is a big mess and we shouldn't follow their example. When
we basically ship one single set of binaries we have at least a chance to
find bugs which people report, when you have to set a huge number of
CONFIG_XXX constants all bets are off.
