Comment (by Thomas Miedema <thomasmiedema@…>):

 In [changeset:"b40e55954ecdab650d35349cbb93e53df952310e/ghc" b40e559/ghc]:

 Build system: simplify *-llvm BuildFlavours (#10223)

 Note that SRC_HC_OPTS are added to every Haskell compilation. So
 there isn't any need to also add `-fllvm` to GhcStage1HcOpts,
 GhcStage2HcOpts and GhcLibHcOpts.

 Small bug fix: make sure we test for -fllvm in SRC_HC_OPTS, to check
 whether the bootstrap compiler is affected by bug #9439.
