Cross-compiling Guile 2.0

[Neil Jerram]

In principle, how should Guile 2.0 be cross-compiled?  I'm thinking
mostly of the part of the build that compiles all the installed modules.

I think target emulation is needed, using QEMU, and in particular that
it wouldn't work to set GUILE_FOR_BUILD to a build-system-native guile,
because that would generate .go files with the wrong architecture.

Alternatively, I suppose another approach would be to defer the module
compilation part of the build until after installation on the target.

Does that sound right?  Are there any other possibilities?

(The target is my Openmoko Freerunner phone.)

Thanks,
