My build includes four post-release commits:

    $ git log --oneline ghc-8.8.2-release..HEAD
    0c81de31db (HEAD -> build-8.8) Remove GHC_STAGE guards from MachDeps
    707ac619a5 TcIface: Fix inverted logic in typechecking of source ticks
    8b193877fe Fix overflow.
    4d59e883b4 Make CorePrep.tryEtaReducePrep and CoreUtils.tryEtaReduce line up

the "HEAD" commit could perhaps help.  My build.mk file is basically
like the sample one with:

    $ diff -U0 mk/build.mk.sample ../ghc-build/build.mk
