ghc-8.4 removed "hs_add_root", see https://downloads.haskell.org/~ghc/8.4.1/docs/html/users_guide/8.4.1-notes.html#runtime-system

This leads to a linker error when building the scoop library for ltsmin.

After this obvious change

diff --git a/src/lib_scoop.c b/src/lib_scoop.c
index ac70f7e..f37cd2b 100644
--- a/src/lib_scoop.c

-    hs_add_root(__stginit_LibScoop);
+    //    hs_add_root(__stginit_LibScoop);
 #endif
     constants=const_empty();
 }

compilation is fine with (tested with ghc-8.6.5, ghc-8.8.1).

I don't know how to test.
