+Makefile: append the CFLAGS to existing ones
+
+Allow the user to pass custom CFLAGS (eg. optimisation flags).
+
+Do not use EXTRA_CFLAGS, append to existing CFLAGS with +=  (Arnout)
+
+Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>
+Cc: Arnout Vandecappelle <arnout@mind.be>

+Patch not sent upstream.
+
+Although not specific to buildroot, I am not sure this is the best
+way to handle user-supplied CFLAGS.
