Okay, those references have nothing to do with it. I'm starting a build
from scratch.

I did find it interesting at the time that your -fno-ret-protector on
the ghc.c.opts actually baked in the argument, not just to the build
process itself, but when I ran the GHC compiler manually on the hello
world.

So I'm gonna rebuild without any of the ghc.c.opts and ghc.link.opts
except the -fno-ret-protector, and I'll see if we can't find other ways
of passing any necessary arguments in the build process without baking
them in.

That means even if we have to make more changes to the Hadrian build
scripts. We've gotten this far, we've made a bunch of changes that
should be upstreamed, we may as well keep going and turn this into a
beautiful PR, not just a beautiful ticket with some patches.

Cheers,
Habib
