Summary: unconfined_execmem_exec_t needed for several GHC-built Haskell binaries

The runtime system for programs compiled by GHC generates code dynamically and
executes it.

The interaction with SELinux's enforcing mode is a known problem, which was
previously addressed with a hack: the %post scripts for Haskell programs were
using chcon to add unconfined_exec_mem_t.  This obviously didn't work in lots of
circumstances, hence wanting to apply the policy properly.

The underlying problem, namely the way GHC allocates memory that it intends to
execute dynamically, should be fixed within the next six months or so.  See
http://hackage.haskell.org/trac/ghc/ticket/738 for details.
