+### Target-specific flags and dependencies
+
+# The generic compilation pattern rule and automatically
+# computed header dependencies (falling back to a dependency on
+# LIB_H) are enough to describe how most targets should be built,
+# but some targets are special enough to need something a little
+# different.
+#
+# - When a source file "foo.c" #includes a generated header file,
+# we need to list that dependency for the "foo.o" target.
+#
+# We also list it from other targets that are built from foo.c
+# like "foo.sp" and "foo.s", even though that is easy to forget
+# to do because the generated header is already present around
+# after a regular build attempt.
+#
+# - Some code depends on configuration kept in makefile
+# variables. The target-specific variable EXTRA_CPPFLAGS can
+# be used to convey that information to the C preprocessor
+# using -D options.
+#
+# The "foo.o" target should have a corresponding dependency on
+# a file that changes when the value of the makefile variable
+# changes. For example, targets making use of the
+# $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
+#
+# Technically the ".sp" and ".s" targets do not need this
+# dependency because they are force-built, but they get the
+# same dependency for consistency. This way, you do not have to
+# know how each target is implemented. And it means the
+# dependencies here will not need to change if the force-build
+# details change some day.
