I believe this is what is accomplished by the attached patch v3. Thanks
to Efraim for the points raised. It turned out that the stack overflow I
was getting attempting to test the previous version was caused by a
circular dependency that was introduced by gcc-boot0 inheriting
perl. This is now fixed.

I spent the last couple hours rebuilding gcc but it failed due to lack
of space on my side... Retrying now but it'll take a few hours before I
can confirm that it works as intended.

Thank you both!
