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? > Until it=E2=80=99s fixed in Guile proper, what do you think of building G= uile > 2.0/2.2/3.0 with #:parallel-build? #f ?

In that case, I would certainly support doing it there.
