That's *because* of compatibility.  It is easy to continue to support
the PDB_OUTPUT_DIRECTORY name in the future and simply ignore it if
the future-named property is set.  If we make SYMBOL_OUTPUT_DIRECTORY
work only for PDB files now then in the future if we make it work for
other toolchains then that will be a change in behavior for existing
projects that expected it to work only for PDB files.
