That was my understanding.

However,
https://bugzilla.redhat.com/show_bug.cgi?id=562980#c3
suggests that it may be possible to install the loader code to 
  /usr/share/gdb/auto-load/lib/ld-%{glibc_version}.so-gdb.py
instead.

We'd still need a:
  Requires: glibc = %{version}
to ensure that we're in sync with glibc.

With this, we could be autoloaded provided that the correct glibc is loaded,
and could issue an error message is glibc-debuginfo not available.

> And since we can't guarantee that the glibc-debuginfo package is installed,

(gdb) heap
Undefined command: "heap".  Try "help".
