27758d8c2583 ("kbuild: enable -Werror for hostprogs") and 7ded7d37e5f5 
("scripts/Makefile.extrawarn: Respect CONFIG_WERROR / W=e for 
hostprogs") (available in v6.18), set

ifneq ($(findstring e, $(KBUILD_EXTRA_WARN))$(CONFIG_WERROR),)
[...]
# While hostprog flags are used during build bootstrapping (thus should not
# depend on CONFIG_ symbols), -Werror is disruptive and should be opted 
into.
# Only apply -Werror to hostprogs built after the initial Kconfig stage.
KBUILD_HOSTCFLAGS       += -Werror
KBUILD_HOSTLDFLAGS      += -Wl,--fatal-warnings
KBUILD_HOSTRUSTFLAGS    += -Dwarnings
endif

so they do it.
