Comment(by StephenBlackheath):

 Here's what's going on: ghc-pwd is built in the final stage and so it's
 for the target. Our iOS compiler generates .a files in place of
 executables, so it produces ghc-pwd.a.

 Unfortunately it's not as simple as just changing exeext to .a, because we
 need to make sure a different exeext is used for host and target
 executables.

 Should I just go through all the exeexts and change them based on whether
 it's host or target? Or is it better to keep it simple and come up with a
 way to avoid ghc-pwd being installed into inplace/bin/ when Stage1Only=YES
 is selected in mk/build.mk (as we do when building cross compilers)?
