Issue tracked at https://gitlab.haskell.org/ghc/ghc/issues/16534
Somehow the stage 2 GHCs (_build/stage1/bin/ghc) that we build _don't_
have this problem. I will post an update here when I have a
comprehensive explanation and a fix.

OK, that’s great – it’s not just me. I’ll await further guidance,
and revert to “sh validate” meanwhile.
Thanks

*Subject:* Re: In-tree invocation of GHC built with Hadrian
I can reproduce this problem. This doesn't come up when building
stage2 with that executable (stage1) because the commands that Hadrian
emits all do something along the lines of `-no-user-package-db
-package-db _build/stage0/lib/package.conf.d`, which masks the
problem. I'm looking into this, I will open a ticket soon with the
information that I can gather.

How can I run the inplace binary built by Hadrian. I tried this
~/code/HEAD/_build/stage0/bin/ghc -c Foo.hs
but I got this
~/code/HEAD/_build/stage0/bin/ghc -c Foo.hs
Foo.hs:1:8: error:

Somehow the inplace binary built by Hadrian is looking for library
files in completely the wrong place.
What should I do?
