I have found LLDB cannot find separate debug info of Fedora /usr/bin/gdb.  It is because:

  lrwxrwxrwx 1 root root       14 Jan 25 20:41 /usr/bin/gdb -> ../libexec/gdb*
  -rwxr-xr-x 1 root root 10180296 Jan 25 20:41 /usr/libexec/gdb*
  ls: cannot access '/usr/lib/debug/usr/bin/gdb-8.0.1-35.fc27.x86_64.debug': No such file or directory
  -r--r--r-- 1 root root 29200464 Jan 25 20:41 /usr/lib/debug/usr/libexec/gdb-8.0.1-35.fc27.x86_64.debug

FYI that `-8.0.1-35.fc27.x86_64.debug` may look confusing, it was always just `.debug` before.
Why is `/usr/bin/gdb` a symlink is offtopic for this bugreport, Fedora has it so for some reasons.

It is always safest to look at the .debug file only after resolving all symlinks on the binary file.  I hope it should not cause any regressions.
