upstream gdb has this same behavior; while the feature is developed by
Red Hat, upstream gdb has the patch to add this feature merged since
quite a while

there is a magic section in the regular elf file that says "look THERE
for my debug info", where "THERE" is the location the debuginfo rpm
installs its files. It's basically a "strip to file" operation, where a
file with debuginfo is split in 2, one is the normal stripped file (but
with a "look THERE" record) and one is only the debuginfo. This is then
packages into seperate rpms.
