-- and Stage1 libraries (including 'compiler') will still be built. Enabling
-- this flag during installation leads to installing @ghc-stage1@ instead of
-- @ghc-stage2@, and @ghc-pkg@ that was build with the Stage0 compiler.
-- Also see Note [No stage2 packages when CrossCompiling or Stage1Only] in the
-- top-level @ghc.mk@.
