Add recipe and patch for nhc98

nhc is an Haskell compiler which is easily bootstrappable from C (unlike
ghc). The downsides are:
- It's slower
- It only implements Haskell 98

It may be usable to build GHC or some other Haskell based software,
we'll see.

+SUMMARY="Standards-compliant compiler for Haskell 98"
+DESCRIPTION="nhc98 is a small, easy to install, standards-compliant compiler \
+for Haskell 98, the :lazy functional programming language. It is very \
+portable, and aims to produce small executables that run in small amounts of \
+memory. It produces medium-fast code, and compilation is itself quite fast. \
+It also comes with extensive tool support for automatic compilation, foreign \
+language interfacing, heap and time profiling, tracing, and debugging. (Some \
+of its advanced kinds of heap profiles are not found in any other Haskell \
+compiler.)"
