Hi,
the trivial patch to debian/rules solves the issue quite good:
diff -u suitesparse-3.4.0/debian/rules suitesparse-3.4.0/debian/rules
--- suitesparse-3.4.0/debian/rules
+++ suitesparse-3.4.0/debian/rules
@@ -12,7 +12,7 @@
DEB_MAKE_BUILD_TARGET := default

-CFLAGS=-fexceptions -Wall -O3
+CFLAGS=-fexceptions -Wall -O3 -g
ifeq ($(DEB_HOST_ARCH_CPU),amd64)
CFLAGS+=-m64
endif
My trivial test then yields:

echo -n "$f " && readelf --debug-dump $f |grep -q . && echo ok || echo fail;

So the only library without dbg symbols is libcsparse.so now.
(non-dbg is the -dbg package from the archive, dbg is my patched
rebuild).
Looking at the build-logs [1], it seems CFLAGS is just not passed into
CSparse/Lib.
This is because CSparse/Lib/Makefile sets CFLAGS itself and ignores what
was set previously. This will have to be patched too. I'd say it should
be something like
-CFLAGS = -O -I../Include
+CFLAGS += -I../Include
(as -O was already set in d/rules)
