`guix environment guix` temporarily installs all software required to
build guix.  I believe this help thread reveals various shortcomings
of the Guix manual.  I had hoped referring to the manual would
suffice, but it obviously is not organized well enough.

You do *not* need guile in your config, but in one of the profiles
that are active when building guix, i.e. you can just run

cd path/to/guix
… # appropriate `git pull --rebase`, `git am ….patch` invocations
guix environment guix
./bootstrap
./configure --localstatedir=/var
make
sudo -E ./pre-inst-env guix system reconfigure /etc/config


I am sorry for all the trouble.  I thought you were originally
applying the patches in a mostly correct way, just on a too old Guix
git revision.
