 The `ghc-heap` library appears to be missing a dependency from
 `GHC.Exts.Heap.Closures` to `GHC.Exts.Heap.InfoTableProf`. This causes the
 vanilla build to fail (in particular when building the profiled way):

    It is a member of the hidden package ‘ghc-heap-8.5’.
    You can run ‘:set -package ghc-heap’ to expose it.
    (Note: this unloads all the modules in the current scope.)
    Use -v to see a list of the files searched for.

 }}}

 Building the `libraries/ghc-heap/dist-
 install/GHC/Exts/Heap/InfoTableProf.p_o` manually allows the build to
 proceed.
