Hadrian: `--configure` is broken
On clean HEAD:
> ./hadrian/build.stack.sh -c -j --flavour=quick
Build system error - indirect recursion detected:
Key value 1: OracleQ (KeyValue ("hadrian/cfg/system.config","cross-compiling"))
Key value 2: hadrian/cfg/system.config
Key value 3: hadrian/cfg/system.config mk/config.h compiler/ghc.cabal rts/rts.cabal
Key value 4: OracleQ (KeyValue ("hadrian/cfg/system.config","gmp-lib-dir"))
Rules may not be recursive
This is because of 09b88384
Patch coming.
