By design limited to the host architecture, but might be good enough
depending on what you want test ...

I've simply used dracut for that in the past.  Recursively sourcing
libraries is one of the things it does which I didn't have to code up
myself that way. Used to work pretty well.

But these days dracut doesn't want give you a shell prompt without
asking for a password beforehand, which is annoying if all you want
do is run some simple tests, and there was to easy way to turn that
off last time I checked ...

take care,
