I will be away for the week-end, but I had a quick look at your changes:
it seems your changes are compiling libraries twice. Recent versions of
gdb are able to handle debugging symbols put in /usr/lib/debug, and we
should use dh_strip(1) to extract those debugging symbols. (That's what
we do in stlport5.1 for instance.)

Besides, according to [1], programs should be compiled with `-g -O2',
then stripped (or in our case, move the debugging symbols into -dbg

I'll investigate further next week.
