aptitude doesn't support installing foreign-architecture
build-dependencies for cross-compiling but apt-get does. aptitude's
interactivity would be very useful when resolving build-deps since it
would help show the reasons for things failing when they do.

# aptitude build-dep -aarmhf libicns
E: Command line option 'a' [from -aarmhf] is not known.
# apt-get build-dep -aarmhf libicns
