I would prefer if the cflags came in via the TARGET_CFLAGS, similar to how the
selected_optimization works. In the past we've hacked around with CFLAGS itself
and in the end it's always seem to have caused problems. By modifing
TARGET_CFLAGS instead, then the user can do (in a recipe):
CFLAGS = "-fmy-custom-flag ${TARGET_CFLAGS}"

Same comment here.
