Thank you for your continued implication that I'm not competent.

I am working on fixing the fact that policy is not properly
documented, please be patient.

However, the entire point of adding `abuild rootbld` was to ensure
that builds were reproducible, so clearly reproducibility is a policy

If you know in your gut, it is a bad approach, then why continue to follow it?

Yes, what I am implying, is that it was never used because it
triggered the same bug.
It was never used because it resulted in erroneous conflicts.

I explained the correct solution already, but will do so again: you
have to break the dependency cycle, by using a bootstrap package.
There is no other way to do it that would allow the build to be reproducible.
But since I am in your eyes incompetent, I am sure you will continue
to ignore this.

It is not.
The GCC contains enough information in the APKBUILD to bootstrap
itself, given an already present C compiler.
In fact, in the process of bootstrapping, *two* GCC packages are created.
See $_bootstrap_configure, $_cross_configure and $_arch_configure for
more details on how these are different.

> So please, don’t interfere into it and wait for reaction from ncopa or fabled.

Please stop implying everyone other than you is incompetent when in
reality you are the one who pushed a broken package that you did not
bother to test under rootbld.
Had you tested under rootbld, you would have known that the builders
would not have accepted the package.
There is no need to wait for bad advice when the correct advice is
already known.
