It looks like this is an issue of using make properly.  The problem is this 
post-patches target:

post-patches::
        aclocal-1.9 -I m4 && autoheader && automake-1.9 && autoconf

As you can see in /usr/share/doc/cdbs/buildcore.png, post-patches is a 
dependency of just about everything, so whenever this target runs, everything 
else needs to be run as well.

I suggest you use an approach with stamp files.  I could make it work like 
this:

post-patches:: autofoo-stamp
autofoo-stamp:
        aclocal-1.9 -I m4 && autoheader && automake-1.9 && autoconf
        touch autofoo-stamp
