Enable -Wcpp-undef
e5b3492f tried (again) to enable -Wcpp-undef in mk/warnings.mk,
SRC_HC_OPTS_STAGE1 += $(WERROR) #-Wcpp-undef
SRC_HC_OPTS_STAGE2 += $(WERROR) #-Wcpp-undefUnfortunately, this caused build failures in boot libraries on some platforms (e.g. time on Darwin). Resolve these and reenable -Wcpp-undef.
An alternative would be to instead only add -Wcpp-undef to GhcRtsHcOpts, GhcStage1HcOpts and GhcStage2HcOpts.
