There doesn't seem to be any relevant difference.

The last mention of -print-multi-os-directory in the ChangeLog is:

2003-01-27  Alexandre Oliva  <aoliva@redhat.com>

        * Makefile.in (install_to_tooldir): Instead of $(MULTISUBDIR), use
        /`$$CC -print-multi-os-directory`.

Which is much earlier than 7.0.

I'm a bit puzzled how this isn't visible with 7.0.

Note that libiberty is "owned" by gcc.
