There are other ways to figure out the dependency in a cross-compiling
environment. We have an internal tool that does just that and more (some
size/fs optimization stuff). It is not used in the current release, though.

The "noarch" means the installed target is arch-independent. The
standard setup in mvista CDK is to let target boot from NFS root fs,
where NFS host can be linux/i386, Linux/ppc and Sun/Sparc (perhaps
Win/i386 as well, I am not sure). Those packages are meant to be
installed to all those hosts, and therefore "noarch" :-0.

Native compiling is easy. Cross-compiling is cool. :-)
Well, not exactly. When you are dealing with head-less, disk-less
memory-scarce embedded devices with ad hoc run-time environments,
cross-compiling is your only choice.
