Usually not.  Nine times out of ten, (probably 99 out of 100) all you
need for cross-devel is the headers and the libraries, and they'll be
in the right place after unpacking.  The package doesn't have to work
in that situation, it just has to be possible to build against it.

Lots of things sould be nice.  It's not an argument for not providing
cross-compilers.

Which we really shouldn't do.  All this is irrelavant, and we're
getting away from the core issue, which is about providing cross
compilers.
