That should be possible. I have no experience with cross-compilation,
but with the right set of csc-options, you can select the desired
compiler and linker, for example.
If you create a custom extension registry (by setting
the environment variable CHICKEN_REGISTRY), you can compile eggs
with cross-compilation tools into a separate registry. The current
CVS version of Chicken has new options for chicken-setup that
allow changing options (or adding new options) at the command line:

$ chicken-setup -options "-cc my-cross-compiler" myegg

Then you can move the whole registry directory to your target machine
(either to $prefix/share/chicken, ~/.chicken-registry, or another directory
if you set CHICKEN-REGISTRY on the target machine).

I haven't tried this, of course. But in principle, this should work.
