Comment (by thomie):
...
I guess we should not put -dynamic in ghcThWayFlags
That doesn't work in batch mode. Take this example:

 A.hs:
 {{{
 {-# LANGUAGE TemplateHaskell #-}
 module A where
 import B
 $(dec)
 }}}

 B.hs:
 {{{
 {-# LANGUAGE TemplateHaskell #-}
 module B where
 import Language.Haskell.TH
 dec = [d| x = 1 |]
 }}}

 Result:
 {{{
 $ ghc -c B.hs
 $ ghc -c A.hs
 A.hs:1:1:
     cannot find normal object file ‘./B.dyn_o’
     while linking an interpreted expression
 }}}

 How about this: when compiling with `-dynamic`, create `.dyn_o` and
 `.dyn_hi` files by default instead of `.o` and `.hi` files. Is there any
 drawback to this? It would be more consistent with what `-dynamic-too`
 does as well.

 `-osuf` and `-hisuf` could keep working as before.
