Do you mean something like this in mk.conf?
pre-build-checks-hook: add-custom-build-cflags
add-custom-build-cflags: .PHONY
${RUN} ${ECHO} 'append=-Werror' \
>>${CWRAPPERS_CONFIG_DIR}/cc
That's indeed pretty simple, feels a bit like a hack (since it's not
easy to choose the "best" hook among those in mk/build/build.mk) but
works perfectly.
