This is a feature.  The debug information for glibc is extremely large,
and it makes GDB take an excessive amount of RAM to debug.  The files
there have a functional .debug_frame and symbol table; this means that
backtraces work, although they would not work without these files.

You can put /usr/lib/debug in LD_LIBRARY_PATH to get debug info, but we
only ship one variant of these.  Again, because they are so large.
