In-tree invocation of GHC built with Hadrian

[Simon Peyton Jones]

No, setting GHC_ENVIRONMNT to "-" doesn't change anything


tmp$ GHC_ENVIRONMENT=- ~/code/HEAD/_build/stage0/bin/ghc -c Foo.hs

| Yes, that looks wrong indeed. It shouldn't pick up the ghc-8.6.4 library.
| 
| After the recent env files discussion, maybe it's picking up some env
| files?

| Does
| 
| GHC_ENVIRONMENT=- ~/code/HEAD/_build/stage0/bin/ghc -c Foo.hs
| 
| yield any better results?
| 
| Cheers,
