I'd recommend starting by editing gnu/packages/make-bootstrap.scm:103
and change the line:
`(("cross-gcc" ,(cross-gcc target
to:
`(("cross-gcc" ,(cross-gcc target #:gcc-6
there are other places, like lines 110 and 391 (and possibly others) which
should be turned to (inherit gcc-6)
That should work for this round, then you can decide if it's worth
upstreaming and wrap it in 'match' keywords for some of the newer
architectures (like riskv).
