Add linking with native libraries to Haskell fpm

[awvwgk]

The link option is available in Fortran fpm and would be a valuable addition for Haskell version as well. Once the Fortran version depends on libraries like libgit2 or libcurl this would be a requirement in Haskell fpm to bootstrap the Fortran version.

This requires to introduce the build table and to propagate the link arguments correctly to the link line in the shake build system.
