Thank you! I hadn't use that so far.

I found no $EPREFIX/tmp/etc, and the fault was reported as already during stage 3,
so I just went with $EPREFIX/etc/portage/package.env and $EPREFIX/etc/portage/env.

It actually did restart from right from bison --- neither its error message,
nor 

  https://www.gentoo.org/proj/en/gentoo-alt/prefix/bootstrap.xml

had induced any hope that it might, so that was a pleasant surprise!

However, there still was a ``make -j5'' during the bison make,
and it failed with a slightly different trace,
but still suggesting that at least three processes were trying to do the same thing,
and ran into a race condition.
I restarted bootstrap-prefix.sh and told it to use -j1,
and the bison build went through.
(Currently it is downloading gcc.)

So bison seems to need -j1.


Thanks a lot!
