Well, do you mean compile-time or run-time. I just tried runtime, i.e.
I did a 
set env LD_LIBRARY_PATH=/usr/lib/debug/lib:... in my .gdbinit.

Now, gdb tells me
>From        To          Syms Read   Shared Object Library
0x055c8040  0x05628d78   No          /lib/libglib-2.0.so.0

without the star which would indicate that no debugging symbols were
found. So, gdb found something, but when I did a bt, there were still
those question marks for libglib. Additionally the program segfaulted
shortly after.
