Comment (by heisenbug):

 Taking the hint from
 https://ghc.haskell.org/trac/ghc/ticket/11239#comment:5 I added `-fno-
 warn-overlapping-patterns -fno-warn-incomplete-patterns` to the
 compilation recipe like this:
 {{{
 ghc -hisuf hi -osuf o -hcsuf hc -static -H64m -O0 -fasm -Wall -package-db
 libraries/bootstrapping.conf -hide-all-packages -i -iutils/genprimopcode/.
 -iutils/genprimopcode/dist/build -iutils/genprimopcode/dist/build/autogen
 -Iutils/genprimopcode/dist/build -Iutils/genprimopcode/dist/build/autogen
 -optP-include -optPutils/genprimopcode/dist/build/autogen/cabal_macros.h
 -package-id array-0.5.1.0 -package-id base-4.9.0.0 -XHaskell2010 -no-user-
 package-db -rtsopts -odir utils/genprimopcode/dist/build -hidir
 utils/genprimopcode/dist/build -stubdir utils/genprimopcode/dist/build -c
 utils/genprimopcode/./Main.hs -o utils/genprimopcode/dist/build/Main.o
 -fno-full-guard-reasoning -fno-warn-overlapping-patterns -fno-warn-
 incomplete-patterns
 }}}
 And it correctly built a `Main.o` and (subsequently on `make`) a
 `genprimopcode` so that I could go on bootstrapping.
