The reason it is not rebuilt is when you are cross-compiling you can't run
mkfeatures.cpp. Typically this is for embedded systems where a static
features file makes reasonable sense.

However, as you suggest, there is no reason why this needs to be the
default behaviour. It would be better to have a flag which means "keep any
existing features file".
