Hi Jesse,

I know very little about what you're trying to do, but there's one thing
that looked wrong to me:

This isn't a build system, right? It's just the package? I think you may
want crosstool-ng-build-system here.

That might be what's causing the error:

Looking in make-bag (in guix/build-system.scm), the first think it does
it pattern match on the build system expecting a record of the
<build-system> type. Your package doesn't match that pattern, so this
error is raised.
