Public bug reported:

In 19.10, perf cannot find the symbols for libc even after installing
libc-dbg.

The symbols for libc are in:

/usr/lib/debug/lib/x86_64-linux-gnu/

but libc is in:

/usr/lib/x86_64-linux-gnu/

so applications expect to find the corresponding symbols at:

/usr/lib/debug/usr/lib/x86_64-linux-gnu/

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete

** Package changed: valgrind (Ubuntu) => linux (Ubuntu)
