bug#74532: with-extensions does not add native extensions to the load path

I'm sorry, I didn't realise that the re-opening of the issue was an
intentional action by a human -- neither the debbugs web interface nor mumi
made this obvious to me. Your first control message doesn't seem to be
reproduced there.

I think I agree with you -- all of this should be handled properly through the
GUILE_* environment variables, without having to patch every single Guile
package individually. With this patch, I mostly wanted to get guile-yamlpp to
work since I needed it for something.

Guile packaging in Guix seems a little strange to me, in general -- e.g. the
treatment for disarchive in <https://issues.guix.gnu.org/62008> might need to
be applied to the Shepherd as well:

--8<---------------cut here--------------->8-
$ guix shell -CN --pure guile shepherd -- guile
scheme@(guile-user)> ,use (shepherd)
While executing meta-command:
no code for module (fibers)
--8<---------------cut here--------------->8-

Cheers,
Timo
