check-ppr not build dynamic for flavour quick-debug

Summary

Running hadrian/build -c -j --flavour=quick-debug test results in check-ppr being build non dynamic

/devel/ghc/master/_build/stage1/bin/ghc -package Cabal -package base -package bytestring -package containers -package directory -package filepath -package ghc -o /devel/ghc/master/_build/test/bin/check-ppr /devel/ghc/master/utils/check-ppr/Main.hs -debug

whereas if flavour quick is used instead of quick-debug check-ppr is build dynamic:

/devel/ghc/master/_build/stage1/bin/ghc -package Cabal -package base -package bytestring -package containers -package directory -package filepath -package ghc -o /devel/ghc/master/_build/test/bin/check-ppr /devel/ghc/master/utils/check-ppr/Main.hs -dynamic

Is this intended? If so can I force check-ppr being build dynamic while using flavour quick-debug?
