Ugh. Thanks for bringing this up again. Would you consider disabling
parallel builds in Guile by default, adding something like a
"--enable-somewhat-faster-non-reproducible-build" configure option until
this is fixed?

Yes, I would support at least doing this.

Are packages using guile-build-system expected to build non-reproducible
too? In that case, I would certainly support doing it there.
