For cross-compiling using ASDF, you might want to have separate features
#+target-iphone and #+target-android separate from the host features.

XCVB indeed completely distinguishes features on the host and target system,
and allows you to define or undefine features with -D and -U.
I don't remember writing a bundling output for ECL on XCVB,
but that could most definitely be done.
Contact me personally or post on the xcvb-devel list if you're interested.
