Override CFLAGS when using cdbs

[Andreas Tille <tillea@rki.de>]

Hi,

I try to package a project that needs to add some include
pathes to the existing default CFLAGS and thus I tried
to patch a Makefile in one subdir to

CFLAGS=$(CFLAGS) -I$(INCLUDEDIR)

but I had to learn that the CFLAGS variable that is used
in the call

  cd subtree; $(MAKE)

just overrides any CFLAGS setting and the line above is
just ignored.  Is there any chance to force setting of
CFLAGS in the makefile?

(Sorry, I guess this is a faq but Google was not friendly
 to my search atempts.)

Kind regards

        Andreas.
