This doesn't work with cdbs/0.4.105:

As an example I've rebuild afuse with current cdbs. CPPFLAGS is not set
through dpkg-buildflags. "-D_FORTIFY_SOURCE=2" should be set instead of
an empty value.

make[1]: Entering directory `/home/jmm/scratch/afuse-0.2'
make[1]: F�r das Ziel �update-config� ist nichts zu tun.
make[1]: Leaving directory `/home/jmm/scratch/afuse-0.2'
touch debian/stamp-autotools-files
chmod a+x /home/jmm/scratch/afuse-0.2/./configure
mkdir -p .
cd . &&   CFLAGS="-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall" CXXFLAGS="-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall" CPPFLAGS="" LDFLAGS="-Wl,-z,relro" /home/jmm/scratch/afuse-0.2/./configure --build=x86_64-linux-gnu  --prefix=/usr --includedir="\${prefix}/include" --mandir="\${prefix}/share/man" --infodir="\${prefix}/share/info" --sysconfdir=/etc --localstatedir=/var --libexecdir="\${prefix}/lib/afuse" --srcdir=. --disable-maintainer-mode --disable-dependency-tracking --disable-silent-rules
