I have been thinking that ExternalProject and cross-compiling might go 
very well together.  You could do host and target builds, and cross 
populate caches and set toolchains automatically in the ExternalProject. 
  I have not tried either, but ExternalProject did not exist when the 
original cross-compile stuff happened, and I think they could really 
complement each other.
