Haskell toolchain for linux

[sajjaphani]

This PR adds the ghc-stage1 package for the x86_64 platform. The GHC package requires libtinfo.so.6, which is typically provided by the ncurses package. However, since ncurses was built with the --enable-widec option, there is no libtinfo.so.6 library (or symbolic link) available by default. To address this, a workaround has been implemented by creating a symlink. Ideally, this issue should be fixed in the ncurses package itself.

We need to investigate the issue reported above to ensure this package is compatible with building the standard core/ghc package before proceeding further.
