Fix #404 Accommodate ${pkgroot} and tolerate GHC errors on Windows #405

CPP is used (sorry) to tailor for Windows and GHC >= 9.0. In that case, ${pkgroot} is not expanded and the bogus prefix is stripped.

Otherwise, ${pkgroot} is expanded. For compatibility with GHC < 9.0, $topdir is still stripped, if present.

I confirm I am licensing my contribution under all licenses that apply to this project (see LICENSE) and that I have no patents covering my contribution.

I can confirm this fixes #420 on ghc-9.4.8 (gentoo linux)
