Symlink in directory causes Cannot build: file does not exist: ghc-prim/.../Classes.hi
Trying out Linux, now, I once again can't build:
```
10:54:28 ~/ghc/ghc> hadrian/build --flavour=devel2 --docs=none

Error, file does not exist and no rule available:
/home/reisenberg/ghc/ghc/_build/stage1/libraries/ghc-prim/build/GHC/Classes.hi
```
I'm bootstrapping from GHC 9.4.3.
-------------------------------------------------------
After some debugging help from @monoidal (see comments below), I've figured out that the problem is that I have a symlink in the directory in which GHC is being built. When I navigate to the actual directory, with no symlinks, then GHC builds fine.
