At a minimum, I'd say you need versions of the glibc libraries with
debugging information available.  On Debian, for example, you would
install the libc6.1-dbg packages, and run gdb with
LD_LIBRARY_PATH=/usr/lib/debug. 

This isn't a binutils thing however, so isn't appropriate for this
list (actually, I'm struggling to think where to take these problems,
probably one of your distribution support lists or IRC -- include what
architecture and some example code for more responses).
