     1Avoid leaking build path into ABI hashes
     2
     3GHC's build path leaks into the ABI hashes it generates by default. This
     4causes problems because it means that recompiling GHC in a different path
     5also requires recompiling all Haskell packages. Obviously, this is
     6undesirable for a distribution.

     1Fix initial build of ghc-pwd due to missing libiconv
     2
     3ghc-pwd fails to build because it is built using ghc-bootstrap, which ships
     4libHSbase-$version.a, which references symbols from libiconv (and actually the
     5system libiconv, because the MacPorts use uses _libiconv as symbol names, but
     6the archive uses _iconv). Fix this by explicitly linking against the system
     7libiconv for this initial build of ghc-pwd.
     8
     9Upstream-Status: Inappropriate (/usr/lib/libiconv.dylib is system-specific; a generic solution would be needed)
