Despite what (guix style) may tell you, revision goes to an extra line.

Should be (which "qbe"), or some elaborate search-input-file.  Also qbe
should be a native input.

I do wonder if some of those get embedded into the compiler or how
they're supposed to be used (outside of build time); if you find a
place where harec invokes qbe, you'd need to patch that in the source.

I don't see why it's necessary to state that harec can't self-host yet.
We would need to bootstrap it from C anyways, so having this
architecture in place actually makes things simpler.
