patch applied (cabal): Allow $arch and $os in install paths.

Tue Jul 29 08:19:52 PDT 2008 Duncan Coutts * Allow $arch and $os in install paths. Fixes ticket #312. For example a user could use: cabal configure --libsubdir="$pkgid/$compiler/$arch" if they wanted to have packages for multiple architectures co-exist in the same filestore area.
