Build with --quickest didn't produce stage1/touchy

[ndmitchell]

I built with hadrian\build.bat -j --flavour=quickest --configure. I then tried to start ghci and got:

GHCi, version 8.7.20180808: http://www.haskell.org/ghc/  :? for help

I copied touchy from stage0 to stage1 and it worked. Does Hadrian ever build touchy in stage1? Should it do so in quickest?

Aha, I didn't realise we need both binaries. We can surely build both, it should be a simple change in GHC/GHC.Packages.

There is also this issue: #595. Do we need to build unlit twice too? If yes, we should close it.

Fixed in #659.
